CC -!- FUNCTION: Catalyzes the aldol cleavage of 4-hydroxy-4-methyl-2- CC oxoglutarate (HMG) into 2 molecules of pyruvate. Also contains a CC secondary oxaloacetate (OAA) decarboxylase activity due to the CC common pyruvate enolate transition state formed following C-C bond CC cleavage in the retro-aldol and decarboxylation reactions (By CC similarity). {ECO:0000250}. CC -!- CATALYTIC ACTIVITY: CC Reaction=4-hydroxy-4-methyl-2-oxoglutarate = 2 pyruvate; CC Xref=Rhea:RHEA:22748, ChEBI:CHEBI:15361, ChEBI:CHEBI:58276; CC EC=4.1.3.17; CC -!- CATALYTIC ACTIVITY: CC Reaction=H(+) + oxaloacetate = CO2 + pyruvate; CC Xref=Rhea:RHEA:15641, ChEBI:CHEBI:15361, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:16452, ChEBI:CHEBI:16526; EC=4.1.1.112; CC -!- COFACTOR: CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240; CC Evidence={ECO:0000250}; CC Note=Divalent metal cation. {ECO:0000250}; CC -!- SUBUNIT: Homotrimer. {ECO:0000250}. CC -!- SIMILARITY: Belongs to the class II aldolase/RraA-like family. CC {ECO:0000305}.
