Gene Rv1909c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Acts as a global negative controlling element, employing FE(2+) as a cofactor to bind the operator of the repressed genes. Seems to regulate transcription of KATG|Rv1908c gene. |
| Product | Ferric uptake regulation protein FurA (fur) |
| Comments | Rv1909c, (MTCY180.09), len: 147 aa. FurA, Ferric uptake regulation protein, similar to Q48835 legionella pneumophila 130B (wadsworth) ferric uptake regulation (136 aa), FASTA results: opt: 230, E(): 2.5e-09, (32.3% identity in 133 aa overlap). Also similar to Mycobacterium tuberculosis zur zinc uptake regulatory protein, Rv2359. Belongs to the fur family. Start changed since original submission (-3 aa). |
| Functional category | Regulatory proteins |
| Proteomics | Identified by proteomics (see proteomics citations). 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 and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (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). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Found to be deleted (partially or completely) in one or more clinical isolates (See Tsolaki et al., 2004). Check for mutants available at TARGET website |
