Does not catalyze the synthesis of 1-aminocyclopropane-1-carboxylate but is capable of catalyzing the deamination of L-vinylglycine. Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family. Similar to plant 1-aminocyclopropane-1-carboxylate synthases but lacks a number of residues which are necessary for activity.
