C00412 ];
2-O-sulfo-alpha,alpha-trehalose [CPD:
C20985 ];
palmitoyl-CoA [CPD:
C00154 ]
Product
2-O-sulfo-2'-stearoyl-alpha,alpha-trehalose [CPD:
C22177 ];
CoA [CPD:
C00010 ];
2-O-sulfo-2'-palmitoyl-alpha,alpha-trehalose [CPD:

Comment
This mycobacterial enzyme catalyses the acylation of 2-O-sulfo-alpha,alpha-trehalose at the 2' position by a C16 or C18 fatty acyl group during the biosynthesis of mycobacterial sulfolipids.
