ID 6.2.1.62 DE 3,4-dihydroxybenzoate--[aryl-carrier protein] ligase. CA 3,4-dihydroxybenzoate + ATP + holo-[aryl-carrier protein] = 3,4- CA dihydroxybenzoyl-[aryl-carrier protein] + AMP + diphosphate. CC -!- The adenylation domain of the enzyme catalyzes the activation of 3,4- CC dihydroxybenzoate to (3,4-dihydroxybenzoyl)adenylate, followed by the CC transfer of the activated compound to the free thiol of a CC phosphopantetheine arm of an aryl-carrier protein domain. CC -!- The aryl-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.
