Accepted name: long-chain-acyl-CoA—trehalose acyltransferase
Reaction: a long-chain-fatty acyl-CoA + α,α-trehalose = a 2-(long-chain-fatty acyl)-trehalose + CoA
Glossary: polyacyltrehalose = PAT = a 2-(long-chain-fatty acyl)-2′,3,4′,6-tetramycolipenoyl-trehalose
a mycolipenoyl-CoA = a (2E,2S,4S,6S)-2,4,6-trimethyl-2-enoyl-CoA
Other name(s): papA3 (gene name)
Systematic name: long-chain-fatty acyl-CoA:α,α-trehalose 2-acyltransferase
Comments: The enzyme, characterized from the bacterium Mycobacterium tuberculosis, participates in the biosynthesis of polyacyltrehalose (PAT), a pentaacylated, trehalose-based glycolipid found in the cell wall of pathogenic strains. The enzyme catalyses two successive activities - it first transfers an acyl (often palmitoyl) group to position 2, followed by the transfer of a mycolipenyl group to position 3 (see EC, mycolipenoyl-CoA—2-(long-chain-fatty acyl)-trehalose mycolipenoyltransferase).
