Figure 10. Structures sulfolipids (SL), diacyltrehaloses (DAT) and polyacyltrehaloses (PAT) and biosynthetic gene clusters.

Figure 10

The major sulfolipid SL-I (2,3,6,6’-tetraacyl α-α’-trehalose-2’-sulfate) is represented. In SL-I, trehalose is sulfated at the 2’ position and esterified with palmitic acid and the multimethyl-branched phthioceranic and hydroxyphthioceranic acids. In DAT (2,3-di-O-acyltrehalose), trehalose is esterified with palmitic acid and the multimethylbranched mycosanoic acid. In PAT, trehalose is esterified with palmitic acid and the multimethyl-branched mycolipenic acids.
