Gene Rv0254c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in cobalamin biosynthesis. |
| Product | Probable bifunctional cobalamin biosynthesis protein CobU: cobinamide kinase + cobinamide phosphate guanylyltransferase |
| Comments | Rv0254c, (MTV034.20), len: 174 aa. Probable cobU, cobalamin biosynthesis protein including a cobinamide kinase and cobinamide phosphate guanylyltransferase. Highly similar to many e.g. Q05599|COBU_SALTY cobinamide kinase / cobinamide phosphate guanylyltransferase from Salmonella typhimurium (181 aa), FASTA scores: opt: 308, E(): 1.1e-14, (38.7% identity in 181 aa overlap); P46886|COBU_ECOLI|B1993|Z3153|ECS2788 Bifunctional cobalamin biosynthesis protein cobU from Escherichia coli strains K12 and O157:H7 (181 aa); part of AL096872|SC5F7_10 from Streptomyces coelicolor (397 aa), FASTA scores: opt: 445, E(): 3.6e-23, (46.0% identity in 176 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop). |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (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). 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 |
