CC   -!- FUNCTION: Catalyzes a cyclopropane ring-opening reaction, the
CC       irreversible conversion of 1-aminocyclopropane-1-carboxylate (ACC) to
CC       ammonia and alpha-ketobutyrate. Allows growth on ACC as a nitrogen
CC       source.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=1-aminocyclopropane-1-carboxylate + H2O = 2-oxobutanoate +
CC         NH4(+); Xref=Rhea:RHEA:16933, ChEBI:CHEBI:15377, ChEBI:CHEBI:16763,
CC         ChEBI:CHEBI:28938, ChEBI:CHEBI:58360; EC=3.5.99.7;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00807};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC   -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_00807}.
CC   -!- SIMILARITY: Belongs to the ACC deaminase/D-cysteine desulfhydrase
CC       family. {ECO:0000255|HAMAP-Rule:MF_00807}.
