Gene Rv0058
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity. The intein is an endonuclease (potential). |
| Product | Probable replicative DNA helicase DnaB |
| Comments | Rv0058, (MTV030.01, MTCY21D4.21), len: 874 aa. Probable dnaB, replicative DNA helicase. Contains an intein (position 61630..62838) similar to, and in the same position as, those in Sycnechocystis and Rhodothermus marinus (see citation below) and C-terminal extein (position 62839..63015) similar to many dnaB proteins. This protein undergoes a protein self splicing that involves a post-translational excision of the intervening region (intein) followed by peptide ligation. Belongs to the helicase family, DNAB subfamily. In the intein section; belongs to the homing endonuclease family. |
| Functional category | Information pathways |
| Proteomics | Identified in the cytosol and cell wall fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
