Synonyms 4-hydroxy-4-methyl-2-ketoglutarate aldolase, 4-hydroxy-4-methyl-2-oxoglutarate aldolase, 4-hydroxy-4-methyl-2-oxoglutarate/4-carboxy-4-hydroxy-2-oxoadipate aldolase, aldolase, 4-hydroxy-4-methyl-2-oxoglutarate, gamma-methyl-gamma-hydroxy-alpha-ketoglutaric aldolase, HMG aldolase, HMG/CHA aldolase, KDPG aldolase, MHK aldolase, MHKG aldolase, pyruvate aldolase
EC Number 4.1.3.17
CAS Registry Number 37290-65-6
Comments Requires a divalent metal ion [3]. This enzyme participates in the degradation of protocatechuate (via the meta-cleavage pathway), phthalate, syringate and gallate [1-3]. The enzyme from?Pseudomonas ochraceae?can also cleave 4-hydroxy-2-oxoglutarate to glyoxylate and pyruvate, and also catalyses the reaction of EC?4.1.1.3?(oxaloacetate decarboxylase) [3].
Cofactor divalent cation
History
Reactions (1) 4-hydroxy-4-methyl-2-oxoglutarate = 2 pyruvate. (2) 2-hydroxy-4-oxobutane-1,2,4-tricarboxylate = oxaloacetate + pyruvate.
