ID 6.2.1.67 DE L-alanine--[L-alanyl-carrier protein] ligase. CA ATP + holo-[peptidyl-carrier protein] + L-alanine = AMP + diphosphate + CA L-alanyl-[peptidyl-carrier protein]. CC -!- The adenylation domain of the enzyme catalyzes the activation of CC L-alanine to (L-alanyl)adenylate, followed by the transfer of the CC activated compound to the free thiol of a phosphopantetheine arm of a CC peptidyl-carrier protein domain. CC -!- The peptidyl-carrier protein domain may be part of the same protein, CC or of a different protein. CC -!- This activity is often found as part of a larger non-ribosomal CC peptide synthase.
