Gene Rv2684
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Thought to be involved in active transport of arsenical compounds across the membrane (export): arsenic resistance by an export mechanism. Responsible for the translocation of the substrate across the membrane. |
| Product | Probable arsenic-transport integral membrane protein ArsA |
| Comments | Rv2684, (MTCY05A6.05), len: 429 aa. Probable arsA, arsenic-transport integral membrane protein, equivalent to P46838|AG45_MYCLE|ML1036 46 KDA probable integral membrane protein (antigen 45, a transmembrane protein related to arsenical pumps) from Mycobacterium leprae (429 aa), FASTA scores: opt: 2067, E(): 9.9e-118, (74.05% identity in 428 aa overlap); and upstream orf O07187|YQ85_MYCTU|ARSB|Rv2685|MT2759|MTCY05A6.06 probable integral membrane 45.2 KDA protein ARSB from Mycobacterium tuberculosis (428 aa), FASTA scores: opt: 2148, E(): 1.3e-122, (76.58% identity in 427 aa overlap). Also highly similar to other proteins e.g. Q9UY19|PAB1107 transport protein from Pyrococcus abyssi (425 aa), FASTA scores: opt: 1109, E(): 8.3e-60, (41.45% identity in 427 aa overlap); O59575|PH1912 hypothetical 46.0 KDA protein from Pyrococcus horikoshii (424 aa), FASTA scores: opt: 1101, E(): 2.5e-59, (41.95% identity in 429 aa overlap); Q9KDI2|BH1231 hypothetical 46.0 KDA protein from Bacillus halodurans (428 aa), FASTA scores: opt: 1018, E(): 2.7e-54, (38.9% identity in 427 aa overlap); etc. Belongs to the NADC/P/PHO87 family of transporters, P subfamily (ARS family). |
| Functional category | Cell wall and cell processes |
| 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, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011).
