Gene Rv0639
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Influences transcription termination and antitermination. Acts as a component of the transcription complex, and interacts with the termination factor rho and RNA polymerase. |
| Product | Probable transcription antitermination protein NusG |
| Comments | Rv0639, (MTCY20H10.20), len: 238 aa. Probable nusG, transcription antitermination protein, equivalent to NP_302283.1|NC_002677 transcription antitermination protein nusG from Mycobacterium leprae (228 aa). Also highly similar to others e.g. P36260|NUSG_STRGR from Streptomyces griseus (294 aa), FASTA scores: opt: 845, E(): 0, (55.4% identity in 233 aa overlap); etc. Note that shorter at the N-terminus than other nusG. Contains PS01014 Transcription termination factor nusG signature. Belongs to the NusG family. |

| Proteomics | The product of this CDS corresponds to spot 3_507 identified in culture supernatant by proteomics at the Max Planck Institute for Infection Biology, Berlin, Germany (see citations below). 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 culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow 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 membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza 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 for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
