Active Site

KDPG/KHG aldolase, active site 1 (IPR031337)

Short name: KDPG/KHG_AS_1


4-Hydroxy-2-oxoglutarate aldolase (EC: (KHG-aldolase) catalyzes the interconversion of 4-hydroxy-2-oxoglutarate into pyruvate and glyoxylate. Phospho-2-dehydro-3-deoxygluconate aldolase (EC: (KDPG-aldolase) catalyzes the interconversion of 6-phospho-2-dehydro-3-deoxy-D-gluconate into pyruvate and glyceraldehyde 3-phosphate. These two enzymes are structurally and functionally related [PMID: 3136164]. They are both homotrimeric proteins of approximately 220 amino-acid residues. They are class I aldolases whose catalytic mechanism involves the formation of a Schiff-base intermediate between the substrate and the epsilon-amino group of a lysine residue. In both enzymes, an arginine is required for catalytic activity.

This site contains the active site arginine.
