ID 6.2.1.n2 DE amino acid--[acyl-carrier-protein] ligase. CA an L-alpha-amino acid + ATP + holo-[ACP] = AMP + an L-alpha-aminoacyl- CA [ACP] + diphosphate. CC -!- Catalyzes the ATP-dependent activation of L-alanine, and to a lesser CC extent of L-glycine and L-serine, and their transfer to the CC phosphopantetheine cofactor covalently attached to a vicinal carrier CC protein. CC -!- May participate in nonribosomal peptide synthesis or related CC processes. CC -!- L-proline and L-glutamate are very poor substrates whereas D-amino CC acids are not substrates for ATP-dependent activation. CC -!- Does not display tRNA aminoacylation activity.
