Gene Rv0490
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Sensor part of a two component regulatory system. Probably forms part of a two-component regulatory system SENX3/REGX3; phosphorylates REGX3. |
| Product | Putative two component sensor histidine kinase SenX3 |
| Comments | Rv0490, (MTCY20G9.16), len: 410 aa. Putative senX3, two-component sensor histidine kinase, transmembrane protein (see citations below), equivalent to O07129|SEX3_MYCBO sensor-like histidine kinase SENX3 from Mycobacterium bovis BCG (410 aa), FASTA scores: E(): 0, (99.5% identity in 410 aa overlap); and highly similar to P54883|SEX3_MYCLE|SENX3 sensor-like histidine kinase from Mycobacterium leprae (443 aa), FASTA score: (83.8% identity in 408 aa overlap). Also highly similar, except in N-terminus, to CAC31957.1|AL583925 probable two-component system sensor histidine kinase from Mycobacterium leprae (441 aa). Also highly similar to sensor kinase proteins from other organisms e.g. CAB77323.1|AL160331 putative sensor kinase protein from Streptomyces coelicolor (426 aa). |
| Functional category | Regulatory proteins |
| Proteomics | Predicted secreted protein - identified in culture filtrates of M. tuberculosis H37Rv; signal peptide predicted (See Malen et al., 2007). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). 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). M. tuberculosis H37Rv senX3-regX3 mutant has reduced ability to survive in THP-1 and bone-marrow-derived macrophages; mutant is attenuated in SCID and DBA/2 mice (See Parish et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Check for mutants available at TARGET website |
