ID   2.5.1.49
DE   O-acetylhomoserine aminocarboxypropyltransferase.
AN   methionine synthase.
AN   O-acetylhomoserine (thiol)-lyase.
AN   O-acetylhomoserine sulfhydrolase.
AN   O-acetyl-L-homoserine acetate-lyase (adding methanethiol).
AN   O-acetyl-L-homoserine sulfhydrolase.
AN   OAH sulfhydrylase.
CA   methanethiol + O-acetyl-L-homoserine = acetate + H(+) + L-methionine.
CC   -!- Also reacts with other thiols and H2S, producing homocysteine or
CC       thioethers.
CC   -!- The name methionine synthase is more commonly applied to EC 2.1.1.13.
CC   -!- The enzyme from Saccharomyces cerevisiae also catalyzes the reaction
CC       of EC 2.5.1.47, but more slowly.
CC   -!- Formerly EC 4.2.99.10.
