Gene Rv2494
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown |
| Product | Possible toxin VapC38. Contains PIN domain. |
| Comments | Rv2494, (MTV008.50), len: 141 aa. Possible vapC38, toxin, part of toxin-antitoxin (TA) operon with Rv2493, contains PIN domain, see Arcus et al. 2005. Similar to others in Mycobacterium tuberculosis e.g. P95023|EMBL:Z83863|MTCY159.26|Rv2530c (139 aa) FASTA scores: opt: 380 E(): 6.6e-19, (48.0% identity in 125 aa overlap); O53372|Rv3320c|MTV016.20c (142 aa), etc. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | 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). 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 |
