  • FUNCTION Catalyzes the formation of 1-aminocyclopropane-1-carboxylate, a direct precursor of ethylene in higher plants (Probable). Involved in defense response by producing ethylene after pathogen infection (PubMed:17012402, PubMed:23031077). Involved in several phosphate deficiency-induced adaptive responses, such as lateral root elongation (PubMed:30810167).CATALYTIC ACTIVITY S-adenosyl-L-methionine = 1-aminocyclopropane-1-carboxylate + S-methyl-5'-thioadenosine + H(+)COFACTOR Alkene biosynthesis; ethylene biosynthesis via S-adenosyl-L-methionine; ethylene from S-adenosyl-L-methionine: step 1/2.INDUCTION Down-regulated by partial submergence (PubMed:9037160). Induced in leaves by infection with the fungal pathogen Magnaporthe oryzae (PubMed:17012402). Induced by phosphate deficency (PubMed:30810167).MISCELLANEOUS Lines with ACS2 transgene under the control of a strong pathogen-inducible promoter show significantly increased levels of endogenous ethylene and defense gene expression in response to pathogen infection, and exhibit increased resistance to Magnaporthe oryzae and Ralstonia solanacearum.SIMILARITY Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family.
