Gene Rv2048c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in biosynthesis of mannosyl-beta-1-phosphomycoketide (MPM) |
| Product | Polyketide synthase Pks12 |
| Comments | Rv2048c, (MTV018.35c), len: 4151 aa. Pks12, polyketide synthase similar to many. Contains 2x PS00012 Phosphopantetheine attachment site, 2x PS00606 Beta-ketoacyl synthases active site, and PS00343 Gram-positive cocci surface proteins 'anchoring' hexapeptide. Nucleotide position 2297976 in the genome sequence has been corrected, G:A resulting in S3004L. |
| Functional category | Lipid metabolism |
| Proteomics | 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 whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Mutant | 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 CDC1551 strain (see Lamichhane et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Essential gene for in vitro growth of H37Rv, and essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). M. tuberculosis H37Rv pks12|Rv2048c mutant does not produce mannosyl-beta-1-phosphomycoketide (MPM) (See Matsunaga et al., 2004). Check for mutants available at TARGET website |
