Gene Rv1876 (bfr)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in iron storage (may perform analogous functions in iron detoxification and storage as that of animal ferritins); ferritin is an intracellular molecule that stores iron in a soluble, nontoxic, readily available form. The functional molecule, which is composed of 24 chains, is roughly spherical and contains a central cavity in which the polymeric ferric iron core is deposited. |
| Product | Probable bacterioferritin BfrA |
| Comments | Rv1876, (MTCY180.42c), len: 159 aa. Probable bfrA (alternate gene name: bfr), bacterioferritin (see citation below), similar to BFR_MYCLE|P43315 bacterioferritin (bfr) from Mycobacterium leprae (159 aa), FASTA results: opt: 958, E(): 0, (90.6% identity in 159 aa overlap). Also similar to Rv3841|MTCY01A6.28c|bfrB possible bacterioferritin from Mycobacterium tuberculosis (181 aa). Belongs to the bacterioferritin family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in carbonate extracts of M. tuberculosis H37Rv membranes using 2DGE and MALDI-MS (See Sinha et al., 2002). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). Identified in the aqueous phase of Triton X-114 extracts of M. tuberculosis H37Rv membranes using 1-DGE, 2-DGE, and MALDI-TOF-MS (See Sinha et al., 2005). Identified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar 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). Disruption of this gene provides a growth advantage 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). 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 |
