N-Acetylneuraminic acid aldolase, also called N-acetylneuraminate lyase (NAL); N-Acetylneuraminic acid aldolase, also called N-acetylneuraminate lyase (NAL), which catalyses the reversible aldol reaction of N-acetyl-D-mannosamine and pyruvate to give N-acetyl-D-neuraminic acid (D-sialic acid). It has a widespread application as biocatalyst for the synthesis of sialic acid and its derivatives. This enzyme has been shown to be quite specific for pyruvate as the donor, but flexible to a variety of D- and, to some extent, L-hexoses and pentoses as acceptor substrates. NAL is member of dihydrodipicolinate synthase family that comprises several pyruvate-dependent class I aldolases.

4-hydroxy-tetrahydrodipicolinate synthase; Members of this family are 4-hydroxy-tetrahydrodipicolinate synthase, previously (incorrectly) called dihydrodipicolinate synthase. It is a homotetrameric enzyme of lysine biosynthesis. E. coli has several paralogs closely related to dihydrodipicoline synthase (DapA), as well as the more distant N-acetylneuraminate lyase. In Pyrococcus horikoshii, the bidirectional best hit with E. coli is to an uncharacterized paralog of DapA, not DapA itself, and it is omitted from the seed. The putative members from the Chlamydias (pathogens with a parasitic metabolism) are easily the most divergent members of the multiple alignment. [Amino acid biosynthesis, Aspartate family]

KDG (2-keto-3-deoxygluconate) aldolases found in archaea; KDG (2-keto-3-deoxygluconate) aldolases found in archaea. This subfamily of enzymes is adapted for high thermostability and shows specificity for non-phosphorylated substrates. The enzyme catalyses the reversible aldol cleavage of 2-keto-3-dexoygluconate to pyruvate and glyceraldehyde, the third step of a modified non-phosphorylated Entner-Doudoroff pathway of glucose oxidation. KDG aldolase shows no significant sequence similarity to microbial 2-keto-3-deoxyphosphogluconate (KDPG) aldolases, and the enzyme shows no activity with glyceraldehyde 3-phosphate as substrate. The enzyme is a tetramer and a member of the DHDPS family of Schiff-base-dependent class I aldolases.

The enzyme is involved in glucarate metabolism, and its mechanism presumbly involves a Schiff-base intermediate similar to members of DHDPS family. While in the case of Pseudomonas sp. 5-dehydro-4-deoxy-D-glucarate is degraded by KDGDH to 2,5-dioxopentanoate, in certain species of Enterobacteriaceae it is degraded instead to pyruvate and glycerate.
