Sysname
(hydroxy)phthioceranyl-[(hydroxy)phthioceranic acid synthase]:2'-acyl-2-O-sulfo-alpha,alpha-trehalose 3'-(hydroxy)phthioceranyltransferase
Reaction(IUBMB)
a (hydroxy)phthioceranyl-[(hydroxy)phthioceranic acid synthase] + 2'-palmitoyl/stearoyl-2-O-sulfo-alpha,alpha-trehalose = a 3'-(hydroxy)phthioceranyl-2'-palmitoyl/stearoyl-2-O-sulfo-alpha,alpha-trehalose + holo-[(hydroxy)phthioceranic acid synthase]
Substrate
(hydroxy)phthioceranyl-[(hydroxy)phthioceranic acid synthase];
2'-palmitoyl/stearoyl-2-O-sulfo-alpha,alpha-trehalose [CPD:
C22096 ]
Product
3'-(hydroxy)phthioceranyl-2'-palmitoyl/stearoyl-2-O-sulfo-alpha,alpha-trehalose;
holo-[(hydroxy)phthioceranic acid synthase]
Comment
This mycobacterial enzyme catalyses the acylation of 2'-palmitoyl/stearoyl-2-O-sulfo-alpha,alpha-trehalose at the 3' position by a (hydroxy)phthioceranoyl group during the biosynthesis of mycobacterial sulfolipids.
