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}.
