| EC | 2.3.1.278 | ||
| Accepted name: | mycolipenoyl-CoA—2-(long-chain-fatty acyl)-trehalose mycolipenoyltransferase | ||
| Reaction: | a mycolipenoyl-CoA + a 2-(long-chain-fatty acyl)-trehalose = a 2-(long-chain-fatty acyl)-3-mycolipenoyl-trehalose + CoA | ||
| Glossary: | a mycolipenoyl-CoA = a (2E,2S,4S,6S)-2,4,6-trimethyl-2-enoyl-CoA polyacyltrehalose = PAT = a 2-(long-chain-fatty acyl)-2′,3,4′,6-tetramycolipenoyl-trehalose |

| Other name(s): | papA3 (gene name) | ||
| Systematic name: | mycolipenoyl-CoA:2-(long-chain-fatty acyl)-trehalose 3-mycolipenoyltransferase | ||
| 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 (see EC 2.3.1.279, long-chain-acyl-CoA—trehalose acyltransferase), followed by the transfer of a mycolipenyl group to position 3. | ||
