in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Respiration |
| Product | Probable ubiquinol-cytochrome C reductase QcrB (cytochrome B subunit) |
| Comments | Rv2196, (MTCY190.07), len: 549 aa. Probable qcrB, Ubiquinol-cytochrome C reductase cytochrome B subunit (cytB), integral membrane protein, low similarity in amino-terminal half to cytochrome b subunits, highly similar at C-terminus to SW:12KD_MYCLE P15878 12 KD protein PIR:S08427 (86.9% identity in 153 aa overlap). FASTA scores: sp|Q45658|QCRB_BACST menaquinol-cytochrome C reductase (224 aa) opt: 341, E(): 6.8e-15; 28.0% identity in 207 aa overlap |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS; predicted transmembrane protein (See Gu et al., 2003). Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS; predicted integral membrane protein (See Xiong et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| 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).
