ID 2.3.1.284 DE 3'-(hydroxy)phthioceranyl-2'-palmitoyl(stearoyl)-2-O-sulfo-trehalose DE (hydroxy)phthioceranyltransferase. CA 3 3'-(hydroxy)phthioceranyl-2'-palmitoyl(stearoyl)-2-O-sulfo-alpha,alpha- CA trehalose = 3,6,6'-tris-(hydroxy)phthioceranyl-2-palmitoyl(stearoyl)- CA 2'-sulfo-alpha-alpha-trehalose + 2 2'-palmitoyl/stearoyl-2-O-sulfo- CA alpha,alpha-trehalose. CC -!- The enzyme, present in mycobacteria, catalyzes the ultimate step in CC the biosynthesis of mycobacterial sulfolipids. CC -!- It catalyzes two successive transfers of a (hydroxy)phthioceranyl CC group from two diacylated intermediates to third diacylated CC intermediate, generating the tetraacylated sulfolipid.
