Gene Rv3082c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | May have a role in the regulation of proteins necessary for virulence. |
| Product | Virulence-regulating transcriptional regulator VirS (AraC/XylS family) |
| Comments | Rv3082c, (MT3167, MTV013.03c), len: 340 aa. VirS, transcriptional regulatory protein araC/xylS family, probably involved in virulence (see citations below). Similar to many transcriptional regulators araC/xylS family e.g. Q9HZ25|PA3215 probable transcriptional regulator (AraC/XylS family) from Pseudomonas aeruginosa (337 aa), FASTA scores: opt: 379, E(): 3e-17, (30.4% identity in 306 aa overlap); Q9Z3Y6|PHBR polyhydroxybutyrate transcriptional activator from Pseudomonas sp. 61-3 (379 aa), FASTA scores: opt: 336, E(): 2e-14, (26.35% identity in 334 aa overlap); P72171|ORUR|PA0831 ornithine utilization transcriptional regulator oruR from Pseudomonas aeruginosa (339 aa), FASTA scores: opt: 274, E(): 1.9e-10, (23.7% identity in 321 aa overlap); Q9ZFW7 virulence regulating homolog from Pseudomonas alcaligenes (346 aa), FASTA scores: opt: 262, E(): 1.2e-09, (24.5% identity in 339 aa overlap); etc. Also similar to O69703|Rv3736|MTV025.084 putative regulatory protein (AraC/XylS family) from Mycobacterium tuberculosis strain H37Rv (353 aa), FASTA scores: opt: 656, E(): 3.5e-35, (36.95% identity in 333 aa overlap). Has potential helix-turn-helix motif at positions 252-273. Belongs to the AraC/XylS family of transcriptional regulators. Substrate of PknK. |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified in the cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Transcriptomics | mRNA identified by DNA microarray analysis and up-regulated at high temperatures (see Stewart et al., 2002). |
| 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 |
