1-Aminocyclopropane-1-Carboxylate Synthase Like Protein (ACCSL)

ACCSL 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.Aminotransferase: An enzyme that catalyzes the transfer of an amino group from a donor molecule to a recipient molecule. Aminotransferases share certain mechanistic features with other pyridoxal-phosphate dependent enzymes, such as the covalent binding of the pyridoxal-phosphate group to a lysine residue. On the basis of sequence similarity, these various enzymes can be grouped into subfamilies; these sequences are defined by the aminotransferases class-I pyridoxal-phosphate attachment site signature, which contains the lysine residue involved in pyridoxal-phosphate binding.
