Gene Rv3236c (kefB)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Probably involved in transport of undetermined substrate (possibly cations Na/H) across the membrane. Thought to be responsible for the translocation of the substrate across the membrane. |
| Product | Probable conserved integral membrane transport protein |
| Comments | Rv3236c, (MTCY20B11.11c), len: 385 aa. Probable conserved integral membrane transport protein, possibly cation (Na/H) transporter, equivalent to Q9CCI5|ML0782 putative transmembrane transport protein from Mycobacterium leprae (385 aa), FASTA scores: opt: 1975, E(): 2.4e-108, (81.55% identity in 385 aa overlap). Highly similar to others e.g. O69958|SC4H2.03c putative transmembrane transport protein from Streptomyces coelicolor (411 aa), FASTA scores: opt: 1226, E(): 1.6e-64, (53.5% identity in 372 aa overlap); Q9XAKO|SC66T3.13c putative transmembrane transport protein from Streptomyces coelicolor (403 aa), FASTA scores: opt: 1198, E(): 6.8e-63, (53.25% identity in 370 aa overlap); Q9RV80|DR1149 putative Na+/H+ antiporter from Deinococcus radiodurans (383 aa), FASTA scores: opt: 1069, E(): 2.3e-55, (47.35% identity in 376 aa overlap); Q9L191|SC10G8.11 putative transmembrane transport protein from Streptomyces coelicolor (446 aa), FASTA scores: opt: 695, E(): 1.9e-33, (38.05% identity in 384 aa overlap); Q9RRW8|DR2367 putative glutathione-regulated potassium-efflux system protein KEFB from Deinococcus radiodurans (575 aa), FASTA scores: opt: 414, E(): 6.2e-17, (30.25% identity in 380 aa overlap); etc. Seems to belong to the CPA2 family. Note that previously known as kefB. |
| 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 the membrane protein fraction 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 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 |
