Gene Rv0267
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in excretion of nitrite produced by the dissimilatory reduction of nitrate. Responsible for the translocation of the substrate across the membrane. |
| Product | Probable integral membrane nitrite extrusion protein NarU (nitrite facilitator) |
| Comments | Rv0267, (MTCY06A4.11), len: 463 aa. Probable narU, nitrite extrusion protein, integral membrane protein possibly member of major facilitator superfamily (MFS), similar to other nitrite extrusion proteins e.g. NARU_ECOLI|P37758 nitrite extrusion protein 2 from Escherichia coli (462 aa), FASTA scores: opt: 630, E(): 4.4e-33, (38.9% identity in 463 aa overlap); and NARK_ECOLI|P10903|B1223 nitrite extrusion protein 1 from Escherichia coli strain K12 (463 aa), FASTA scores: opt: 607, E(): 1.3e-31, (42.0% identity in 457 aa overlap). Also similar to Rv0261c, Rv2329c, Rv1737c, and to MLCB22_25 from Mycobacterium leprae (517 aa), FASTA score: (35.1 identity in 459 aa overlap). Belongs to the nark/NASA family of transporters. |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). |
| Mutant | Non-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 provides a growth advantage 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 |
