Gene Rv2871
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown |
| Product | Possible antitoxin VapB43 |
| Comments | Rv2871, (MTCY274.02), len: 85 aa. Possible vapB43, antitoxin, part of toxin-antitoxin (TA) operon with Rv2872, see Arcus et al. 2005. Similar to others in Mycobacterium tuberculosis strains H37Rv and CDC1551 e.g. O50456|Rv1241|MTV006.13 (86 aa), FASTA scores: opt: 172, E(): 2.9e-05, (37.2% identity in 86 aa overlap); O53811|Rv0748|MTV041.22 (85 aa), FASTA scores: opt: 170, E(): 4e-05, (35.3% identity in 85 aa overlap); etc. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified in the cell membrane fraction 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). |
| 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). Check for mutants available at TARGET website |
