Gene Rv1843c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in GMP biosynthesis [catalytic activity: inosine 5'-phosphate + NAD+ + H2O = xanthosine 5'-phosphate + NADH] |
| Product | Probable inosine-5'-monophosphate dehydrogenase GuaB1(imp dehydrogenase) (IMPDH) (IMPD) |
| Comments | Rv1843c, (MTCY359.30), len: 479 aa. Probable guaB1, inosine-5'-monophosphate dehydrogenase. Similar to others e.g. IMDH_BACSU|P21879 from Bacillus subtilis (513 aa), FASTA score: opt: 904, E(): 0, (37.8% identity in 471 aa overlap). Similar to other Mycobacterium tuberculosis proteins e.g. guaB2, Rv3411c. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by proteomics at the Statens Serum Institute (Denmark) (See Rosenkrands et al., 2000). 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 cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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). |
| 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 |
