Gene Rv1547
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The alpha chain is the DNA polymerase [catalytic activity: N deoxynucleoside triphosphate = N diphosphate + {DNA}(N)]. |
| Product | Probable DNA polymerase III (alpha chain) DnaE1 (DNA nucleotidyltransferase) |
| Comments | Rv1547, (MTCY48.18c), len: 1184 aa. Probable dnaE1, DNA polymerase III, alpha chain (see citation below), similar to many e.g. DP3A_ECOLI|P10443 dna polymerase III, alpha chain (1160 aa), FASTA scores: opt: 1789, E(): 0, (36.5% identity in 1193 aa overlap). Also similar to M. tuberculosis, DnaE2|Rv3370c. Belongs to DNA polymerase type-C family, DNAE subfamily. |
| Functional category | Information pathways |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| 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).
