Gene Rv3245c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Sensor part of a two component regulatory system. |
| Product | Two component sensory transduction histidine kinase MtrB |
| Comments | Rv3245c, (MTCY20B11.20c), len: 567 aa. MtrB, sensor-like histidine kinase (see citations below), equivalent to Q9CCJ1|MTRB or ML0774 putative two-component system sensor kinase from Mycobacterium leprae (562 aa), FASTA scores: opt: 3208, E(): 7.4e-173, (88.7% identity in 566 aa overlap). Also similar to others e.g. Q9KYW9|SCE33.14c putative two-component system histidine kinase from Streptomyces coelicolor (688 aa), FASTA scores: opt: 1355, E(): 1.1e-68, (48.95% identity in 515 aa overlap); etc. Relatives in Mycobacterium tuberculosis are: MTCY369.03, E(): 1.5e-22; MTCY20G9.16, E(): 1.9e-17. Similar to other prokaryotic sensory transduction histidine kinases. |
| Functional category | Regulatory proteins |
| Proteomics | Identified in the cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene results in growth defect of H37Rv in vitro, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
