Gene Rv2947c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Polyketide synthase possibly involved in lipid synthesis |
| Product | Probable polyketide synthase Pks15 |
| Comments | Rv2947c, (MTCY24G1.02), len: 496 aa. Probable pks15, polyketide synthase. Almost identical to G560508|Q50469 PKS002B protein from Mycobacterium tuberculosis (495 aa), FASTA scores: opt: 3270, E(): 0, (99.6% identity in 496 a a overlap). Similar to Mycobacterium tuberculosis proteins MTCY338.20|RV2931|PPSA_MYCTU ppsA phenolpthiocerol synthesis (1876 aa) (49.9% identity in 465 aa overlap); MTCY24G1.09|RV2940C|P96291 Putative mas, mycocerosic acid synthase (2111 aa) (50.2% identity in 454 aa overlap); and MTCY22H8.03|RV2382C|P71718 hypothetical protein (444 aa) (47.6% identity in 437 aa overlap). Contains PS00606 Beta-ketoacyl synthases active site. Note pks15 has been shown to be involved in the biosynthesis of phthiocerol. pks15/pks1 has been shown to be involved in the biosynthesis of phenolphthiocerol glycolipids. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 24h of starvation (see citation below). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-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, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
