Reaction: ATP + 4-hydroxybenzoate + holo-[4-hydroxyphenylalkanoate synthase] = AMP + diphosphate + 4-hydroxybenzoyl-[4-hydroxyphenylalkanoate synthase] (overall reaction)
(1a) ATP + 4-hydroxybenzoate = 4-hydroxybenzoyl-adenylate + diphosphate
(1b) 4-hydroxybenzoyl-adenylate + holo-[4-hydroxyphenylalkanoate synthase] = AMP + 4-hydroxybenzoyl-[4-hydroxyphenylalkanoate synthase]
Other name(s): fadD22 (gene name); 4-hydroxybenzoate adenylase
Systematic name: 4-hydroxybenzoate:holo-[4-hydroxyphenylalkanoate synthase] ligase (AMP-forming)
Comments: This mycobacterial enzyme participates in the biosynthesis of phenolphthiocerols. Following the substrate‘s activation by adenylation, it is transferred to an acyl-carrier protein domain within the enzyme, from which it is transferred to EC 2.3.1.261, 4-hydroxyphenylalkanoate synthase.
