ID 2.3.1.279 DE long-chain-acyl-CoA--trehalose acyltransferase. CA a long-chain fatty acyl-CoA + alpha,alpha-trehalose = 2-O-(long-chain CA fatty acyl)-alpha,alpha-trehalose + CoA. CC -!- The enzyme, characterized from the bacterium Mycobacterium CC tuberculosis, participates in the biosynthesis of polyacyltrehalose CC (PAT), a pentaacylated, trehalose-based glycolipid found in the cell CC wall of pathogenic strains. CC -!- The enzyme catalyzes two successive activities - it first transfers CC an acyl (often palmitoyl) group to position 2, followed by the CC transfer of a mycolipenyl group to position 3 (see EC 2.3.1.278).
