Gene Rv1340
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | RNase PH is a phosphorolytic exoribonuclease that removes nucleotide residues following the -CCA terminus of tRNA and adds nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates [catalytic activity: {tRNA}(N+1) + phosphate = {tRNA}(N) + a nucleoside diphosphate]. |
| Product | Probable ribonuclease RphA (RNase PH) (tRNA nucleotidyltransferase) |
| Comments | Rv1340, (MTCY130.25), len: 259 aa. Probable rphA, Ribonuclease ph, highly similar to others e.g. RNPH_MYCLE|P37939 Mycobacterium leprae (259 aa), FASTA scores: opt: 1524, E(): 0, (88.8% identity in 259 aa overlap). Belongs to the RNASE PH family. |
| 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 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). 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 strain (see Sassetti et al., 2003). Check for mutants available at TARGET website |
