Accepted name: L-arginine—[L-arginyl-carrier protein] ligase
Reaction: ATP + L-arginine + holo-[L-arginyl-carrier protein] = AMP + diphosphate + L-arginyl-[L-arginyl-carrier protein] (overall reaction)
(1a) ATP + L-arginine = diphosphate + (L-arginyl)adenylate
(1b) (L-arginyl)adenylate + holo-[L-arginyl-carrier protein] = AMP + L-arginyl-[L-arginyl-carrier protein]
Other name(s): vabF (gene name)
Systematic name: L-arginine:[L-arginyl-carrier protein] ligase (AMP-forming)
Comments: The adenylation domain of the enzyme catalyses the activation of L-arginine to (L-arginyl)adenylate, followed by the transfer of the activated compound to the free thiol of a phosphopantetheine arm of a peptidyl-carrier protein domain. The peptidyl-carrier protein domain may be part of the same protein, or of a different protein. This activity is often found as part of a larger non-ribosomal peptide synthase.
