2.3.1.288

Accepted name:

2-O-sulfo trehalose long-chain-acyltransferase

Reaction:

(1) stearoyl-CoA + 2-O-sulfo-α,α-trehalose = 2-O-sulfo-2′-stearoyl-α,α-trehalose + CoA
(2) palmitoyl-CoA + 2-O-sulfo-α,α-trehalose = 2-O-sulfo-2′-palmitoyl-α,α-trehalose + CoA

Other name(s):

papA₂ (gene name)

Systematic name:

acyl-CoA:2-O-sulfo-α,α-trehalose 2′-long-chain-acyltransferase

Comments:

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