Rossmann-fold NAD(P)(+)-binding proteins; A large family of proteins that share a Rossmann-fold NAD(P)H/NAD(P)(+) binding (NADB) domain. The NADB domain is found in numerous dehydrogenases of metabolic pathways such as glycolysis, and many other redox enzymes. NAD binding involves numerous hydrogen-bonds and van der Waals contacts, in particular H-bonding of residues in a turn between the first strand and the subsequent helix of the Rossmann-fold topology. Characteristically, this turn exhibits a consensus binding pattern similar to GXGXXG, in which the first 2 glycines participate in NAD(P)-binding, and the third facilitates close packing of the helix to the beta-strand. Typically, proteins in this family contain a second domain in addition to the NADB domain, which is responsible for specifically binding a substrate and catalyzing a particular enzymatic reaction.

Phosphoglycerate dehydrogenases, NAD-binding and catalytic domains; Phosphoglycerate dehydrogenases (PGDHs) catalyze the initial step in the biosynthesis of L-serine from D-3-phosphoglycerate. PGDHs come in 3 distinct structural forms, with this first group being related to 2-hydroxy acid dehydrogenases, sharing structural similarity to formate and glycerate dehydrogenases. PGDH in E. coli and Mycobacterium tuberculosis form tetramers, with subunits containing a Rossmann-fold NAD binding domain. Formate/glycerate and related dehydrogenases of the D-specific 2-hydroxyacid dehydrogenase superfamily include groups such as formate dehydrogenase, glycerate dehydrogenase, L-alanine dehydrogenase, and S-adenosylhomocysteine hydrolase. Despite often low sequence identity, these proteins typically have a characteristic arrangement of 2 similar subdomains of the alpha/beta Rossmann fold NAD+ binding form. The NAD+ binding domain is inserted within the linear sequence of the mostly N-terminal catalytic domain, which has a similar domain structure to the internal NAD binding domain. Structurally, these domains are connected by extended alpha helices and create a cleft in which NAD is bound, primarily to the C-terminal portion of the 2nd (internal) domain. Some related proteins have similar structural subdomain but with a tandem arrangement of the catalytic and NAD-binding subdomains in the linear sequence.

fungal a-factor pheromone receptor STE3, member of the class D family of seven-transmembrane G protein-coupled receptors; This subfamily represents the a-factor pheromone receptor encoded by the STE3 gene, which is required for pheromone sensing and mating in haploid cells of the yeast Saccharomyces cerevisiae. The STE3-encoded seven-transmembrane domain receptor is a member of the class D GPCRs. Class D receptors are composed of two major subfamilies: Ste2 and Ste3. These two GPCRs (Ste2 and Ste3) sense the polypeptide mating pheromones, alpha-factor and a-factor, which activate a G protein-coupled receptors on the surface of the opposite yeast-mating haploid-types (MATa and MAT-alpha), respectively. Activation of these receptors by pheromones leads to activation of the mitogen-activated protein kinase (MAPK) signal transduction cascades, G1 cell cycle arrest, and polarized cell growth in the direction of the partner cell (a process called shmooing), which ultimately induces cell-cell fusion and the formation of a diploid zygote. Like all GPCRs, these pheromone mating factor receptors possess the same basic architecture of seven-transmembrane (7TM) domains and share common signaling mechanisms; however, there is no significant sequence similarity either between Ste2 and Ste3, or between these two receptors and the other 7TM GPCRs. Thus, STE2 and STE3 represent phylogenetically distinct groups.

Formate/glycerate and related dehydrogenases of the D-specific 2-hydroxy acid dehydrogenase family; Formate dehydrogenase, D-specific 2-hydroxy acid dehydrogenase, Phosphoglycerate Dehydrogenase, Lactate dehydrogenase, Thermostable Phosphite Dehydrogenase, and Hydroxy(phenyl)pyruvate reductase, among others, share a characteristic arrangement of 2 similar subdomains of the alpha/beta Rossmann fold NAD+ binding form. 2-hydroxyacid dehydrogenases are enzymes that catalyze the conversion of a wide variety of D-2-hydroxy acids to their corresponding keto acids. The general mechanism is (R)-lactate + acceptor to pyruvate + reduced acceptor. The NAD+ binding domain is inserted within the linear sequence of the mostly N-terminal catalytic domain, which has a similar domain structure to the internal NAD binding domain. Structurally, these domains are connected by extended alpha helices and create a cleft in which NAD is bound, primarily to the C-terminal portion of the 2nd (internal) domain. Some related proteins have similar structural subdomain but with a tandem arrangement of the catalytic and NAD-binding subdomains in the linear sequence. Formate dehydrogenase (FDH) catalyzes the NAD+-dependent oxidation of formate ion to carbon dioxide with the concomitant reduction of NAD+ to NADH. FDHs of this family contain no metal ions or prosthetic groups. Catalysis occurs though direct transfer of hydride ion to NAD+ without the stages of acid-base catalysis typically found in related dehydrogenases. FDHs are found in all methylotrophic microorganisms in energy production and in the stress responses of plants. Formate/glycerate and related dehydrogenases of the D-specific 2-hydroxyacid dehydrogenase superfamily include groups such as formate dehydrogenase, glycerate dehydrogenase, L-alanine dehydrogenase, and S-Adenosylhomocysteine Hydrolase, among others. While many members of this family are dimeric, alanine DH is hexameric and phosphoglycerate DH is tetrameric.

D-glycerate dehydrogenase/hydroxypyruvate reductase (GDH); D-glycerate dehydrogenase (GDH, also known as hydroxypyruvate reductase, HPR) catalyzes the reversible reaction of (R)-glycerate + NAD+ to hydroxypyruvate + NADH + H+. In humans, HPR deficiency causes primary hyperoxaluria type 2, characterized by over-excretion of L-glycerate and oxalate in the urine, possibly due to an imbalance in competition with L-lactate dehydrogenase, another formate dehydrogenase (FDH)-like enzyme.

D-Lactate and related Dehydrogenases, NAD-binding and catalytic domains; D-Lactate dehydrogenase (LDH) catalyzes the interconversion of pyruvate and lactate, and is a member of the 2-hydroxyacid dehydrogenase family. LDH is homologous to D-2-Hydroxyisocaproic acid dehydrogenase (D-HicDH) and shares the 2 domain structure of formate dehydrogenase. D-HicDH is a NAD-dependent member of the hydroxycarboxylate dehydrogenase family, and shares the Rossmann fold typical of many NAD binding proteins. D-HicDH from Lactobacillus casei forms a monomer and catalyzes the reaction R-CO-COO(-) + NADH + H+ to R-COH-COO(-) + NAD+. Similar to the structurally distinct L-HicDH, D-HicDH exhibits low side-chain R specificity, accepting a wide range of 2-oxocarboxylic acid side chains. (R)-2-hydroxyglutarate dehydrogenase (HGDH) catalyzes the NAD-dependent reduction of 2-oxoglutarate to (R)-2-hydroxyglutarate. Formate/glycerate and related dehydrogenases of the D-specific 2-hydroxyacid dehydrogenase superfamily include groups such as formate dehydrogenase, glycerate dehydrogenase, L-alanine dehydrogenase, and S-adenosylhomocysteine hydrolase. Despite often low sequence identity, these proteins typically have a characteristic arrangement of 2 similar subdomains of the alpha/beta Rossmann fold NAD+ binding form.

Structurally, these domains are connected by extended alpha helices and create a cleft in which NAD is bound, primarily to the C-terminal portion of the 2nd (internal) domain. Some related proteins have similar structural subdomain but with a tandem arrangement of the catalytic and NAD-binding subdomains in the linear sequence. While many members of this family are dimeric, alanine DH is hexameric and phosphoglycerate DH is tetrameric.

C-terminal ACT (regulatory) domain of D-3-Phosphoglycerate Dehydrogenase (3PGDH) found in fungi and bacteria; The C-terminal ACT (regulatory) domain of D-3-Phosphoglycerate Dehydrogenase (3PGDH) found in fungi and bacteria. 3PGDH is an enzyme that belongs to the D-isomer specific, 2-hydroxyacid dehydrogenase family and catalyzes the oxidation of D-3-phosphoglycerate to 3- phosphohydroxypyruvate, which is the first step in the biosynthesis of L-serine, using NAD+ as the oxidizing agent. In Escherichia coli, the SerA 3PGDH is feedback-controlled by the end product L-serine in an allosteric manner. In the homotetrameric enzyme, the interface at adjacent ACT (regulatory) domains couples to create an extended beta-sheet. Each regulatory interface forms two serine-binding sites. The mechanism by which serine transmits inhibition to the active site is postulated to involve the tethering of the regulatory domains together to create a rigid quaternary structure with a solvent-exposed active site cleft. Members of this CD belong to the superfamily of ACT regulatory domains.

Formate/glycerate dehydrogenases, D-specific 2-hydroxy acid dehydrogenases and related dehydrogenases; The formate/glycerate dehydrogenase like family contains a diverse group of enzymes such as formate dehydrogenase (FDH), glycerate dehydrogenase (GDH), D-lactate dehydrogenase, L-alanine dehydrogenase, and S-Adenosylhomocysteine hydrolase, that share a common 2-domain structure. Despite often low sequence identity, these proteins typically have a characteristic arrangement of 2 similar domains of the alpha/beta Rossmann fold NAD+ binding form. The NAD(P) binding domain is inserted within the linear sequence of the mostly N-terminal catalytic domain. Structurally, these domains are connected by extended alpha helices and create a cleft in which NAD(P) is bound, primarily to the C-terminal portion of the 2nd (internal) domain. While many members of this family are dimeric, alanine DH is hexameric and phosphoglycerate DH is tetrameric. 2-hydroxyacid dehydrogenases are enzymes that catalyze the conversion of a wide variety of D-2-hydroxy acids to their corresponding keto acids. The general mechanism is (R)-lactate + acceptor to pyruvate + reduced acceptor. Formate dehydrogenase (FDH) catalyzes the NAD+-dependent oxidation of formate ion to carbon dioxide with the concomitant reduction of NAD+ to NADH. FDHs of this family contain no metal ions or prosthetic groups. Catalysis occurs though direct transfer of a hydride ion to NAD+ without the stages of acid-base catalysis typically found in related dehydrogenases.

ACT_3PGDH-like CD includes the C-terminal ACT (regulatory) domain of D-3-phosphoglycerate dehydrogenase (3PGDH); ACT_3PGDH-like: The ACT_3PGDH-like CD includes the C-terminal ACT (regulatory) domain of D-3-phosphoglycerate dehydrogenase (3PGDH), with or without an extended C-terminal (xct) region found in various bacteria, archaea, fungi, and plants. 3PGDH is an enzyme that belongs to the D-isomer specific, 2-hydroxyacid dehydrogenase family and catalyzes the oxidation of D-3-phosphoglycerate to 3- phosphohydroxypyruvate, which is the first step in the biosynthesis of L-serine, using NAD+ as the oxidizing agent.

This CD also includes the C-terminal ACT domain of the L-serine dehydratase (LSD), iron-sulfur-dependent, beta subunit, found in various bacterial anaerobes such as Clostridium, Bacillus, and Treponema species. LSD enzymes catalyze the deamination of L-serine, producing pyruvate and ammonia. Unlike the eukaryotic L-serine dehydratase, which requires the pyridoxal-5'-phosphate (PLP) cofactor, the prokaryotic L-serine dehydratase contains an [4Fe-4S] cluster instead of a PLP active site. The LSD alpha and beta subunits of the 'clostridial' enzyme are encoded by the sdhA and sdhB genes. The single subunit bacterial homologs of L-serine dehydratase (LSD1, LSD2, TdcG) present in E. coli, and other Enterobacteriales, lack the ACT domain described here. Members of this CD belong to the superfamily of ACT regulatory domains.

seven-transmembrane G protein-coupled receptor superfamily; This hierarchical evolutionary model represents the seven-transmembrane (7TM) receptors, often referred to as G protein-coupled receptors (GPCRs), which transmit physiological signals from the outside of the cell to the inside via G proteins. GPCRs constitute the largest known superfamily of transmembrane receptors across the three kingdoms of life that respond to a wide variety of extracellular stimuli including peptides, lipids, neurotransmitters, amino acids, hormones, and sensory stimuli such as light, smell and taste. All GPCRs share a common structural architecture comprising of seven-transmembrane (TM) alpha-helices interconnected by three extracellular and three intracellular loops. A general feature of GPCR signaling is agonist-induced conformational changes in the receptors, leading to activation of the heterotrimeric G proteins, which consist of the guanine nucleotide-binding G-alpha subunit and the dimeric G-beta-gamma subunits. The activated G proteins then bind to and activate numerous downstream effector proteins, which generate second messengers that mediate a broad range of cellular and physiological processes. However, some 7TM receptors, such as the type 1 microbial rhodopsins, do not activate G proteins. Based on sequence similarity, GPCRs can be divided into six major classes: class A (the rhodopsin-like family), class B (the Methuselah-like, adhesion and secretin-like receptor family), class C (the metabotropic glutamate receptor family), class D (the fungal mating pheromone receptors), class E (the cAMP receptor family), and class F (the frizzled/smoothened receptor family). Nearly 800 human GPCR genes have been identified and are involved essentially in all major physiological processes. Approximately 40% of clinically marketed drugs mediate their effects through modulation of GPCR function for the treatment of a variety of human diseases including bacterial infections.

S-Adenosylhomocysteine Hydrolase, NAD-binding and catalytic domains; S-adenosyl-L-homocysteine hydrolase (SAHH, AdoHycase) catalyzes the hydrolysis of S-adenosyl-L-homocysteine (AdoHyc) to form adenosine (Ado) and homocysteine (Hcy). The equilibrium lies far on the side of AdoHyc synthesis, but in nature the removal of Ado and Hyc is sufficiently fast, so that the net reaction is in the direction of hydrolysis. Since AdoHyc is a potent inhibitor of S-adenosyl-L-methionine dependent methyltransferases, AdoHycase plays a critical role in the modulation of the activity of various methyltransferases. The enzyme forms homotetramers, with each monomer binding one molecule of NAD+.
