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 common
CC pyruvate enolate transition state formed following C-C bond cleavage in
CC the retro-aldol and decarboxylation reactions (By similarity).
CC {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; Xref=Rhea:RHEA:15641,
CC ChEBI:CHEBI:15361, ChEBI:CHEBI:15378, ChEBI:CHEBI:16452,
CC 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}.
