2.3.1.278 a mycolipenoyl-CoA + a 2-(long-chain-fatty acyl)-trehalose the enzyme participates in the biosynthesis of polyacyltrehalose, a pentaacylated, trehalose-based glycolipid found in the cell wall of pathogenic strains 446088 2.3.1.278 a mycolipenoyl-CoA + a 2-(long-chain-fatty acyl)-trehalose the enzyme catalyses two successive activities. It first transfers an acyl (often palmitoyl) group to position 2 (see EC 2.3.1.279, long-chain-acyl-CoA-trehalose acyltransferase), followed by the transfer of a mycolipenyl group to position 3 446088
