Octanoylation is a rare process in nature and several of the octanoyltransferases known to date are involved in fatty acid metabolism. LipB (EC 2.3.1.181) participates in the synthesis of lipoic acid, a highly conserved organosulfur cofactor derived from octanoic acid, which is essential in aerobic bacteria and eukaryotes49.
