FunctionInvolved in the final steps of mycolic acid biosynthesis. Catalyses the condensation of two fatty acyl chains.
ProductPolyketide synthase Pks13
CommentsRv3800c, (MTV026.05c), len: 1733 aa. Probable pks13, polyketide synthase, equivalent to Q9CDB1|PKS13|ML0101 polyketide synthase from Mycobacterium leprae (1784 aa), FASTA scores: opt: 7454, E(): 0, (83.6% identity in 1748 aa overlap); and similar to Q9Z5K6|ML2357|MLCB12.02c putative polyketide synthase from Mycobacterium leprae (1871 aa), FASTA scores: opt: 1682, E(): 1.2e-85, (38.3% identity in 1096 aa overlap). Also similar in part to many e.g. Q9ADL6|SORA soraphen polyketide synthase a from Polyangium cellulosum (6315 aa) FASTA scores: opt: 1422, E(): 1e-70, (31.45% identity in 1616 aa overlap); AAK73501|AMPHI AMPHI protein (involved in amphotericin biosynthesis) from Streptomyces nodosus (9510 aa), FASTA scores: opt: 1441, E(): 1.2e-71, (30.45% identity in 1662 aa overlap); Q9RFL0|MTAB MTAB protein (involved in myxothiazol biosynthesis) from Stigmatella aurantiaca (4003 aa), FASTA scores: opt: 1429, E(): 2.8e-71, (33.8% identity in 1089 aa overlap); Q9L4X2|NYSJ from Streptomyces noursei (5435 aa), FASTA scores: opt: 1407, E(): 6.1e-70, (30.5% identity in 1764 aa overlap); CAC37876|SC1G7.01c from Streptomyces coelicolor (3489 aa) FASTA scores: opt: 1382, E(): 1e-68, (31.05% identity in 1489 aa overlap); etc. Also highly similar to Q10977|PPSA_MYCTU|Rv2931|MT3000|MTCY338.20 phenolpthiocerol synthesis polyketide synthase from Mycobacterium tuberculosis (1876 aa), FASTA scores: opt: 1728, E(): 3.4e-88, (36.95% identity in 1269 aa overlap); and P96203|PPSD|Rv2934|MTCY19H9.02. Contains PS00606 Beta-ketoacyl synthases active site.

ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011).
