EC 6.2.1.62     
Accepted name: 3,4-dihydroxybenzoate—[aryl-carrier protein] ligase
Reaction: ATP + 3,4-dihydroxybenzoate + holo-[aryl-carrier protein] = AMP + diphosphate + 3,4-dihydroxybenzoyl-[aryl-carrier protein] (overall reaction)
(1a) ATP + 3,4-dihydroxybenzoate = diphosphate + (3,4-dihydroxybenzoyl)adenylate
(1b) (3,4-dihydroxybenzoyl)adenylate + holo-[aryl-carrier protein] = AMP + 3,4-dihydroxybenzoyl-[aryl-carrier protein]
Other name(s): asbC (gene name)
Systematic name: 3,4-dihydroxybenzoate:[aryl-carrier protein] ligase (AMP-forming)
Comments: The adenylation domain of the enzyme catalyses the activation of 3,4-dihydroxybenzoate to (3,4-dihydroxybenzoyl)adenylate, followed by the transfer of the activated compound to the free thiol of a phosphopantetheine arm of an aryl-carrier protein domain. The aryl-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.
