ProductPolyketide synthase Pks2
CommentsRv3825c, (MTCY409.05), len: 2126 aa. pks2, polyketide synthase (see citation below), equivalent to Q9CD78|mas|ML0139 putative mycocerosic synthase from Mycobacterium leprae (2116 aa), FASTA scores: opt: 6828, E(): 0, (63.3% identity in 2128 aa overlap); and Q49624|PKS3|MASA|ML1229|B1170_C2_209 probable mycocerosic acid synthase from Mycobacterium leprae (2118 aa) FASTA scores: opt: 5220, E(): 0, (62.4% identity in 2130 aa overlap); or similar in part to others from Mycobacterium leprae e.g. Q9CB70|ML2354 polyketide synthase (1822 aa) FASTA scores: opt: 2787, E(): 2.1e-145, (34.7% identity in 2135 aa overlap). Also highly similar to Q02251|MCAS_MYCBO|mas mycocerosic acid synthase from Mycobacterium bovis (2110 aa), FASTA scores: opt: 3495, E(): 2.6e-184, (61.65% identity in 2130 aa overlap). Also highly similar to other polyketide synthases from Mycobacterium tuberculosis e.g. O53901|PKS5|Rv1527c|MTV045.01c|MTCY19G5.01 (2108 aa) FASTA scores: opt: 9576, E(): 0, (69.8% identity in 2124 aa overlap); P96291|mas|Rv2940c|MTCY24G1.09|MTCY19H9.08c (2111 aa), FASTA scores: opt: 3518, E(): 1.4e-185, (64.05% identity in 2126 aa overlap); O50437|PKS4|Rv1181|MTV005.17 (1582 aa), FASTA scores: opt: 3461, E(): 1.6e-182, (64.55% identity in 1609 aa overlap); etc. Contains PS00606 Beta-ketoacyl synthases active site and PS00012 Phosphopantetheine attachment site.
Functional categoryLipid metabolism
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 the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
TranscriptomicsmRNA identified by SCOTS method, 48h after infection of cultured human primary macrophages (see Graham & Clark-Curtiss 1999). mRNA also identified by microarray analysis and up-regulated after 96h of starvation (see Betts et al., 2002). DNA microarrays show higher level of expression in M. tuberculosis H37Rv than in phoP|Rv0757 mutant (See Walters et al., 2006).
MutantNon-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011).
