Function
function
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).
Catalytic activity
- 4-hydroxy-4-methyl-2-oxoglutarate = 2 pyruvate
Cofactor
Note: Divalent metal cation.
