Gene Rv2856
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Seems involved in nickel incorporation. Thought to be involved in transport of nickel across the membrane. Responsible for the translocation of the substrate across the membrane. |
| Product | Possible nickel-transport integral membrane protein NicT |
| Comments | Rv2856, (MTCY24A1.01c), len: 372 aa. Possible nicT, nickel-transport integral membrane protein, similar to transport proteins and hydrogenase cluster proteins e.g. BAB58860|SAV2698 hypothetical 37.9 KDA protein from Staphylococcus aureus subsp. aureus Mu50 (338 aa), FASTA scores: opt: 1082, E(): 7.1e-60, (48.05% identity in 335 aa overlap); Q97ZB2|HOXN high-affinity nickel-transport protein from Sulfolobus solfataricus (373 aa), FASTA scores: opt: 922, E(): 6.6e-50, (42.2% identity in 372 aa overlap); P23516|HOXN_ALCEU high-affinity nickel transport protein (integral membrane protein) from Alcaligenes eutrophus (Ralstonia eutropha) (351 aa), FASTA scores: opt: 904, E(): 8.3e-49, (41.9% identity in 339 aa overlap); Q45247|HUPN_BRAJA hydrogenase nickel incorporation protein from Bradyrhizobium japonicum (381 aa), FASTA scores: opt: 853, E(): 1.3e-45, (41.65% identity in 329 aa overlap); etc. Seems to belong to the HOXN/HUPN/NIXA family of nickel transporters (NiCoT family). |
| 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). |
| 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). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website |
