Trehalose synthase TreS; Catalyzes the reversible interconversion of maltose and trehalose by transglucosylation. Also displays amylase activity, catalyzing the endohydrolysis of (1->4)-alpha-D- glucosidic linkages in glycogen and maltooligosaccharides such as maltoheptaose, to produce maltose which then can be converted to trehalose. TreS plays a key role in the utilization of trehalose for the production of glycogen and alpha-glucan via the TreS-Pep2 branch involved in the biosynthesis of maltose-1-phosphate (M1P). Might also function as a sensor and/or regulator of trehalose levels [...]

Rv0204c, (MTV033.12c), len: 412 aa. Probable conserved transmembrane protein (see citation below),equivalent, but has C-terminal extension, to Z95398|MLCL622.17c from Mycobacterium leprae (367 aa),FASTA scores: opt: 2002, E(): 0, (82.4% identity in 374 aa overlap). Some similarity to Rv0585c from Mycobacterium tuberculosis. Nucleotide position 242299 in the genome sequence has been corrected, C:G resulting in V306L.

Possible conserved polyketide synthase associated protein PapA2; Catalyzes the acylation of trehalose-2-sulfate by adding the palmitoyl group at the 2'-position to yield the intermediate trehalose- 2-sulfate-2'-palmitate (SL659) during the cell wall sulfolipid-1 (SL-1) biosynthesis; Belongs to the PapA acyltransferase family.

Conserved polyketide synthase associated protein PapA1; Catalyzes the acylation of trehalose-2-sulfate-2'-palmitate (SL659) by adding the (hydroxy)phthioceranoyl group at the 3'-position to yield the diacylated intermediate 2-palmitoyl-3-(C43)-phthioceranyl- alpha, alpha'-D-trehalose-2'-sulfate (SL1278) during the cell wall sulfolipid-1 (SL-1) biosynthesis; Belongs to the PapA acyltransferase family.

Probable conserved polyketide synthase associated protein PapA3; Involved in the biosynthesis of polyacyltrehalose (PAT) which could have a role in anchoring the bacterial capsule. In vitro catalyzes the sequential transfer of two palmitoyl groups onto a single glucose residue of trehalose generating the diacylated product 2,3- diacyltrehalose (trehalose dipalmitate). Although palmitoyl-CoA (PCoA) seems to be the physiological acyl donor, PapA3 can also use docosanoyl (22-carbon saturated fatty acid) coenzyme A as acyl donor.
