Accepted name: 4-hydroxyphenylalkanoate adenylyltransferase FadD29
Reaction: (1) ATP + 17-(4-hydroxyphenyl)heptadecanoate + holo-[(phenol)carboxyphthiodiolenone synthase] = AMP + diphosphate + 17-(4-hydroxyphenyl)heptadecanoyl-[(phenol)carboxyphthiodiolenone synthase]
(1a) ATP + 17-(4-hydroxyphenyl)heptadecanoate = diphosphate + 17-(4-hydroxyphenyl)heptadecanoyl-adenylate
(1b) 17-(4-hydroxyphenyl)heptadecanoyl-adenylate + holo-[(phenol)carboxyphthiodiolenone synthase] = AMP + 17-(4-hydroxyphenyl)heptadecanoyl-[(phenol)carboxyphthiodiolenone synthase]
(2) ATP + 19-(4-hydroxyphenyl)nonadecanoate + holo-[(phenol)carboxyphthiodiolenone synthase] = AMP + diphosphate + 19-(4-hydroxyphenyl)nonadecanoyl-[(phenol)carboxyphthiodiolenone synthase]
(2a) ATP + 19-(4-hydroxyphenyl)nonadecanoate = diphosphate + 19-(4-hydroxyphenyl)nonadecanoyl-adenylate
(2b) 19-(4-hydroxyphenyl)nonadecanoyl-adenylate + holo-[(phenol)carboxyphthiodiolenone synthase] = AMP + 19-(4-hydroxyphenyl)nonadecanoyl-[(phenol)carboxyphthiodiolenone synthase]
Other name(s): fadD29 (gene name); 4-hydroxyphenylalkanoate adenylase
Systematic name: 4-hydroxyphenylalkanoate:holo-[(phenol)carboxyphthiodiolenone synthase] ligase
Comments: The 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 the phenolphthiocerol/phthiocerol polyketide synthase.
