ATPase, P-type (transporting), HAD superfamily, subfamily IC; The P-type ATPases are a large family of trans-membrane transporters acting on charged substances. The distinguishing feature of the family is the formation of a phosphorylated intermediate (aspartyl-phosphate) during the course of the reaction. Another common name for these enzymes is the E1-E2 ATPases based on the two isolable conformations: E1 (unphosphorylated) and E2 (phosphorylated). Generally, P-type ATPases consist of only a single subunit encompassing the ATPase and ion translocation pathway, however, in the case of the potassium (TIGR01497) and sodium/potassium (TIGR01106) varieties, these functions are split between two subunits. Additional small regulatory or stabilizing subunits may also exist in some forms. P-type ATPases are nearly ubiquitous in life and are found in numerous copies in higher organisms (at least 45 in Arabidopsis thaliana, for instance). Phylogenetic analyses have revealed that the P-type ATPase subfamily is divided up into groups based on substrate specificities and this is represented in the various subfamily and equivalog models that have been made: IA (K+) TIGR01497, IB (heavy metals) TIGR01525, IIA1 (SERCA-type Ca++) TIGR01116, IIA2 (PMR1-type Ca++) TIGR01522, IIB (PMCA-type Ca++) TIGR01517, IIC (Na+/K+, H+/K+ antiporters) TIGR01106, IID (fungal-type Na+ and K+) TIGR01523, IIIA (H+) TIGR01647, IIIB (Mg++) TIGR01524, IV (phospholipid, flippase) TIGR01652 and V (unknown specificity) TIGR01657. The crystal structure of one calcium-pumping ATPase and an analysis of the fold of the catalytic domain of the P-type ATPases have been published. These reveal that the catalytic core of these enzymes is a haloacid dehalogenase(HAD)-type aspartate-nucleophile hydrolase. The location of the ATP-binding loop in between the first and second HAD conserved catalytic motifs defines these enzymes as members of subfamily I of the HAD superfamily (see also TIGR01493, TIGR01509, TIGR01549, TIGR01544 and TIGR01545). Based on these classifications, the P-type ATPase _superfamily_ corresponds to the IC subfamily of the HAD superfamily.

2.53e-26
animal plasma membrane Ca2(+)-ATPases (PMCA), similar to human ATP2B1-4/PMCA1-4, and related Ca2(+)-ATPases including Saccharomyces cerevisiae vacuolar PMC1; Animal PMCAs function to export Ca(2+) from cells and play a role in regulating Ca(2+) signals following stimulus induction and in preventing calcium toxicity. Many PMCA pump variants exist due to alternative splicing of transcripts. PMCAs are regulated by the binding of calmodulin or by kinase-mediated phosphorylation. Saccharomyces cerevisiae vacuolar transporter Pmc1p facilitates the accumulation of Ca2+ into vacuoles. Pmc1p is not regulated by direct calmodulin binding but responds to the calmodulin/calcineurin-signaling pathway and is controlled by the transcription factor complex Tcn1p/Crz1p. Similarly, the expression of the gene for Dictyostelium discoideum Ca(2+)-ATPase PAT1, patA, is under the control of a calcineurin-dependent transcription factor. Plant vacuolar Ca(2+)-ATPases, are regulated by direct-calmodulin binding. Plant Ca(2+)-ATPases are present at various cellular locations including the plasma membrane, endoplasmic reticulum, chloroplast and vacuole. This subfamily belongs to the P-type ATPases, a large family of integral membrane transporters that are of critical importance in all kingdoms of life. They generate and maintain (electro-) chemical gradients across cellular membranes, by translocating cations, heavy metals and lipids, and are distinguished from other main classes of transport ATPases (F- , V- , and ABC- type) by the formation of a phosphorylated (P-) intermediate state in the catalytic cycle.

plasma-membrane calcium-translocating P-type ATPase; This model describes the P-type ATPase responsible for translocating calcium ions across the plasma membrane of eukaryotes, out of the cell. In some organisms, this type of pump may also be found in vacuolar membranes. In humans and mice, at least, there are multiple isoforms of the PMCA pump with overlapping but not redundant functions. Accordingly, there are no human diseases linked to PMCA defects, although alterations of PMCA function do elicit physiological effects. The calcium P-type ATPases have been characterized as Type IIB based on a phylogenetic analysis which distinguishes this group from the Type IIA SERCA calcium pump. A separate analysis divides Type IIA into sub-types (SERCA and PMR1) which are represented by two corresponding models (TIGR01116 and TIGR01522). This model is well separated from those.

sarco/endoplasmic reticulum Ca(2+)-ATPase (SERCA), similar to mammalian ATP2A1-3/SERCA1-3; SERCA is a transmembrane (Ca2+)-ATPase and a major regulator of Ca(2+) homeostasis and contractility in cardiac and skeletal muscle. It re-sequesters cytoplasmic Ca(2+) to the sarco/endoplasmic reticulum store, thereby also terminating Ca(2+)-induced signaling such as in muscle contraction. Three genes (ATP2A1-3/SERCA1-3) encode SERCA pumps in mammals, further isoforms exist due to alternative splicing of transcripts.

They generate and maintain (electro-) chemical gradients across cellular membranes, by translocating cations, heavy metals and lipids, and are distinguished from other main classes of transport ATPases (F- , V- , and ABC- type) by the formation of a phosphorylated (P-) intermediate state in the catalytic cycle.

P-type heavy metal-transporting ATPase, similar to human copper-transporting ATPases, ATP7A and ATP7B; The mammalian copper-transporting P-type ATPases, ATP7A and ATP7B are key molecules required for the regulation and maintenance of copper homeostasis. Menkes and Wilson diseases are caused by mutation in ATP7A and ATP7B respectively. This subfamily includes other copper-transporting ATPases such as: Bacillus subtilis CopA , Archeaoglobus fulgidus CopA, and Saccharomyces cerevisiae Ccc2p. This subclass of P-type ATPase is also referred to as CPx-type ATPases because their amino acid sequences contain a characteristic CPC or CPH motif associated with a stretch of hydrophobic amino acids and N-terminal ion-binding sequences. This subfamily belongs to the P-type ATPases, a large family of integral membrane transporters that are of critical importance in all kingdoms of life. They generate and maintain (electro-) chemical gradients across cellular membranes, by translocating cations, heavy metals and lipids, and are distinguished from other main classes of transport ATPases (F- , V- , and ABC- type) by the formation of a phosphorylated (P-) intermediate state in the catalytic cycle.

P-type heavy metal-transporting ATPase; Heavy metal-transporting ATPases (Type IB ATPases) transport heavy metal ions (Cu(+), Cu(2+), Zn(2+), Cd(2+), Co(2+), etc.) across biological membranes. These ATPases include mammalian copper-transporting ATPases, ATP7A and ATP7B, Bacillus subtilis CadA which transports cadmium, zinc and cobalt out of the cell, Bacillus subtilis ZosA/PfeT which transports copper, and perhaps also zinc and ferrous iron, Archaeoglobus fulgidus CopA and CopB, Staphylococcus aureus plasmid pI258 CadA, a cadmium-efflux ATPase, and Escherichia coli ZntA which is selective for Pb(2+), Zn(2+), and Cd(2+). The characteristic N-terminal heavy metal associated (HMA) domain of this group is essential for the binding of metal ions. This family belongs to the P-type ATPases, a large family of integral membrane transporters that are of critical importance in all kingdoms of life. They generate and maintain (electro-) chemical gradients across cellular membranes, by translocating cations, heavy metals and lipids, and are distinguished from other main classes of transport ATPases (F- , V- , and ABC- type) by the formation of a phosphorylated (P-) intermediate state in the catalytic cycle.

alpha-subunit of Na(+)/K(+)-ATPases and of gastric H(+)/K(+)-ATPase, similar to the human Na(+)/K(+)-ATPase alpha subunits 1-4; This subfamily includes the alpha subunit of Na(+)/K(+)-ATPase a heteromeric transmembrane protein composed of an alpha- and beta-subunit and an optional third subunit belonging to the FXYD proteins which are more tissue specific regulatory subunits of the enzyme. The alpha-subunit is the catalytic subunit responsible for transport activities of the enzyme. This subfamily includes all four isotopes of the human alpha subunit: (alpha1-alpha4, encoded by the ATP1A1- ATP1A4 genes). Na(+)/K(+)-ATPase functions chiefly as an ion pump, hydrolyzing one molecule of ATP to pump three Na(+) out of the cell in exchange for two K(+)entering the cell per pump cycle. In addition Na(+)/K(+)-ATPase acts as a signal transducer. This subfamily also includes Oreochromis mossambicus (tilapia) Na(+)/K(+)-ATPase alpha 1 and alpha 3 subunits, and gastric H(+)/K(+)-ATPase which exchanges hydronium ion with potassium and is responsible for gastric acid secretion. Gastric H(+)/K(+)-ATPase is an alpha,beta-heterodimeric enzyme. This subfamily belongs to the P-type ATPases, a large family of integral membrane transporters that are of critical importance in all kingdoms of life. They generate and maintain (electro-) chemical gradients across cellular membranes, by translocating cations, heavy metals and lipids, and are distinguished from other main classes of transport ATPases (F- , V- , and ABC- type) by the formation of a phosphorylated (P-) intermediate state in the catalytic cycle.
