Family

KDPG/KHG aldolase (IPR000887)

Short name: Aldlse_KDPG_KHG

Family relationships

None.

Description

4-Hydroxy-2-oxoglutarate aldolase (EC:4.1.3.16) (KHG-aldolase) catalyzes the interconversion of 4-hydroxy-2-oxoglutarate into pyruvate and glyoxylate. Phospho-2-dehydro-3-deoxygluconate aldolase (EC:4.1.2.14) (KDPG-aldolase) catalyzes the interconversion of 6-phospho-2-dehydro-3-deoxy-D-gluconate into pyruvate and glyceraldehyde 3-phosphate. E. coli Eda is a KDPG-aldolase that has also been found to have a role in the degradation of 2-keto-4-hydroxyglutarate (KHG) to pyruvate and glyoxylate [PMID: 4894280]. In fact, KHG-aldolase and Eda are the same enzyme [PMID: 15659677].

This family consists of KHG/KDPG aldolases, and also includes 2-keto-3-deoxy-6-phosphogalactonate (KDPGal) aldolase. KDPGal-aldolase catalyzes an identical reaction to KDPG, differing in substrate specificity in only the configuration of a single stereocentre [PMID: 17981470].
