FunctionInvolved in excretion of nitrite produced by the dissimilatory reduction of nitrate. Responsible for the translocation of the substrate across the membrane.
ProductProbable integral membrane nitrite extrusion protein NarK3 (nitrite facilitator)
CommentsRv0261c, (MTCY06A4.05c), len: 469 aa. Probable nirK3, nitrite extrusion protein, integral membrane protein possibly member of major facilitator superfamily (MFS), equivalent to AAB41700.1|U72744 nitrite extrusion protein from Mycobacterium fortuitum (471 aa); and 2342627|CAB11406.1|Z98741|T44908 nitrite extrusion protein homolog from Mycobacterium leprae (517 aa; longer in N-terminus). Also similar to other nitrite extrusion proteins e.g. NARK_ECOLI|P10903|B1223 nitrite extrusion protein 1 from Escherichia coli strain K12 (463 aa), FASTA scores: opt: 755, E(): 0, (35.0% identity in 466 aa overlap). Belongs to the nark/NASA family of transporters.
Functional categoryCell wall and cell processes
MutantNon-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 strain (see Sassetti et al., 2003).
