CC   -!- FUNCTION: Catalyzes the formation of 1-aminocyclopropane-1-carboxylate,
CC       a direct precursor of ethylene in higher plants.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=S-adenosyl-L-methionine = 1-aminocyclopropane-1-carboxylate +
CC         H(+) + S-methyl-5'-thioadenosine; Xref=Rhea:RHEA:21744,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:17509, ChEBI:CHEBI:58360,
CC         ChEBI:CHEBI:59789; EC=4.4.1.14;
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC   -!- PATHWAY: Alkene biosynthesis; ethylene biosynthesis via S-adenosyl-L-
CC       methionine; ethylene from S-adenosyl-L-methionine: step 1/2.
CC   -!- SUBUNIT: Homodimer.
CC   -!- SIMILARITY: Belongs to the class-I pyridoxal-phosphate-dependent
CC       aminotransferase family. {ECO:0000305}.
