CC   -!- FUNCTION: Involved in the ethylmalonyl-CoA pathway for acetate
CC       assimilation. Catalyzes the reversible condensation of glyoxylate and
CC       acetyl-CoA to L-malyl-CoA and the reversible condensation of glyoxylate
CC       and propionyl-CoA to yield beta-methylmalyl-CoA (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(S)-malyl-CoA = acetyl-CoA + glyoxylate; Xref=Rhea:RHEA:16629,
CC         ChEBI:CHEBI:36655, ChEBI:CHEBI:57288, ChEBI:CHEBI:57317; EC=4.1.3.24;
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2R,3S)-beta-methylmalyl-CoA = glyoxylate + propanoyl-CoA;
CC         Xref=Rhea:RHEA:38259, ChEBI:CHEBI:36655, ChEBI:CHEBI:57392,
CC         ChEBI:CHEBI:75634; EC=4.1.3.24;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC       Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC       Note=Divalent cations such as magnesium or manganese. {ECO:0000250};
CC   -!- SUBUNIT: Homohexamer. Dimer of trimers (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the HpcH/HpaI aldolase family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ACL99930.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
