Gene Rv1737c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in excretion of nitrite, produced by the dissimilatory reduction of nitrate, across the membrane. Responsible for the translocation of the substrate across the membrane. |
| Product | Possible nitrate/nitrite transporter NarK2 |
| Comments | Rv1737c, (MTCY04C12.22c), len: 395 aa. Possible narK2, nitrate/nitrite-transport integral membrane protein (see Hutter & Dick 2000), possibly member of major facilitator superfamily (MFS), similar to P46907|NARK_BACSU nitrite extrusion protein from Bacillus subtilis (395 aa), FASTA scores: opt: 742, E(): 0, (33.6% identity in 375 aa overlap); and to AL109989|SCJ12.23 hypothetical nitrate/nitrite transporter from Streptomyces coelicolor (412 aa), FASTA scores: opt: 1181, E(): 0, (49.4% identity in 389 aa overlap). |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 and 90 days (See Kruh 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). |
| Transcriptomics | mRNA identified by DNA microarray analysis: gene induced by hypoxia (see Sherman et al., 2001), and down-regulated after 4h and 96h of starvation (see Betts 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 |
