Protein

Putative 4-hydroxy-4-methyl-2-oxoglutarate aldolase

Gene

VV1_0547

Organism
Vibrio vulnificus (strain CMCP6)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the aldol cleavage of 4-hydroxy-4-methyl-2-oxoglutarate (HMG) into 2 molecules of pyruvate. Also contains a secondary oxaloacetate (OAA) decarboxylase activity due to the common pyruvate enolate transition state formed following C-C bond cleavage in the retro-aldol and decarboxylation reactions (By similarity).By similarity

Catalytic activityi

4-hydroxy-4-methyl-2-oxoglutarate = 2 pyruvate.
Oxaloacetate = pyruvate + CO2.
