Gene Rv2299c (Rv2299)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Molecular chaperone involved in protein folding. Has ATPase activity. |
| Product | Probable chaperone protein HtpG (heat shock protein) (HSP90 family protein) (high temperature protein G) |
| Comments | Rv2299c, (MTCY339.11), len: 647 aa. HtpG, probable chaperone, heat shock protein 90 family. Similar to HTPG_BACSU|P46208 heat shock protein htpG homologue from Bacillus subtilis (626 aa), FASTA scores: opt: 1551, E(): 0, (39.6% identity in 631 aa overlap). Contains possible helix-turn-helix motif at aa 519-540 (+3.77 SD). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified by proteomics at the Statens Serum Institute (Denmark) (See Rosenkrands et al., 2000). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). 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). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Transcriptomics | DNA microarrays show lower level of expression in M. tuberculosis H37Rv than in phoP|Rv0757 mutant (See Walters et al., 2006). |
| 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 strain (see Sassetti 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 |
