Gene Rv1020 (trcF)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in nucleotide excision repair. Necessary for strand-specific repair. A lesion in the template strand blocks the RNA polymerase complex (RNAP). The RNAP-DNA-RNA complex is specifically recognized by TRCF which releases RNAP and the truncated transcript; the TCRF may replace RNAP at the lesion site and then recruit the UVRA/B/C repair system. |
| Product | Probable transcription-repair coupling factor Mfd (TRCF) |
| Comments | Rv1020, (MTCY10G2.29c), len: 1234 aa. Probable mfd (alternate gene name: trcF), transcription-repair coupling factor (see citation below), similar to many e.g. MFD_ECOLI|P30958 transcription-repair coupling factor from Escherichia coli (1148 aa), FASTA scores: opt: 1900, E(): 0, (37.9% identity in 1107 aa overlap); similar to M. tuberculosis Rv2973c and Rv1633. Contains PS00017 ATP/GTP-binding site motif A (P-loop). In the N-terminal section; belongs to the UVRB family. In the C-terminal section; belongs to the helicase family. RECG 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 in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). 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 |
