EC 6.2.1.59 Details
EC number
6.2.1.59
Accepted name
long-chain fatty acid adenylase/transferase FadD26
Reaction
ATP + a long-chain fatty acid + holo-[(phenol)carboxyphthiodiolenone synthase] = AMP + diphosphate + a long-chain acyl-[(phenol)carboxyphthiodiolenone synthase] (overall reaction);;(1a) ATP + a long-chain fatty acid = diphosphate + a long-chain fatty-acyl adenylate ester;;(1b) a long-chain fatty-acyl adenylate ester + holo-[(phenol)carboxyphthiodiolenone synthase] = AMP + a long-chain acyl-[(phenol)carboxyphthiodiolenone synthase]
Other name(s)
FadD26
Systematic name
long-chain fatty acid:holo-[(phenol)carboxyphthiodiolenone synthase] ligase (AMP-forming)
Comment
The enzyme, present in pathogenic species of mycobacteria, participates in the pathway for biosynthesis of phthiocerols. It catalyses the adenylation of the long-chain fatty acids arachidate (C20) or behenate (C22) [1] and potentially the very-long-chain fatty acid lignocerate (C24) [2]. The activated fatty acids are then loaded to EC 2.3.1.292, (phenol)carboxyphthiodiolenone synthase.
