| Accepted name: |
3′-(hydroxy)phthioceranyl-2′-palmitoyl(stearoyl)-2-O-sulfo-trehalose (hydroxy)phthioceranyltransferase |
| Reaction: |
3 3′-(hydroxy)phthioceranyl-2′-palmitoyl(stearoyl)-2-O-sulfo-α,α-trehalose = 3,6,6′-tris-(hydroxy)phthioceranyl-2-palmitoyl(stearoyl)-2′-sulfo-α-alpha-trehalose + 2 2′-palmitoyl/stearoyl-2-O-sulfo-α,α-trehalose |
| Glossary: |
3,6,6′-tris-(hydroxy)phthioceranyl-2-palmitoyl(stearoyl)-2′-sulfo-α-alpha-trehalose = a mycobacterial sulfolipid |
| Other name(s): |
chp1 (gene name) |
| Systematic name: |
3′-(hydroxy)phthioceranyl-2′-palmitoyl(stearoyl)-2-O-sulfo-α,α-trehalose:3′-(hydroxy)phthioceranyl-2′-palmitoyl(stearoyl)-2-O-sulfo-α,α-trehalose 6,6′-di(hydroxy)phthioceranyltransferase |
| Comments: |
The enzyme, present in mycobacteria, catalyses the ultimate step in the biosynthesis of mycobacterial sulfolipids. It catalyses two successive transfers of a (hydroxy)phthioceranyl group from two diacylated intermediates to third diacylated intermediate, generating the tetraacylated sulfolipid. |
