Gene Rv2973c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Critical role in recombination and DNA repair. Help process holliday junction intermediates to mature products by catalysing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3' to 5' polarity. RECG unwind branched duplex DNA (Y-DNA). |
| Product | Probable ATP-dependent DNA helicase RecG |
| Comments | Rv2973c, (MTCY349.14), len: 737 aa. Probable recG, ATP-dependent DNA helicase (see citation below), equivalent to O69460|RECG_MYCLE ATP-dependent DNA helicase from Mycobacterium leprae (743 aa), FASTA scores: opt: 3846, E(): 0, (79.3% identity in 744 aa overlap). Also highly similar to others e.g. Q9ZBR3|SC7A1.10 putative ATP-dependent DNA helicase from Streptomyces coelicolor (742 aa), FASTA scores: opt: 1249, E(): 1.1e-67, (46.2% identity in 758 aa overlap); Q9PGE8 ATP-dependent DNA helicase from Xylella fastidiosa (718 aa), FASTA scores: opt: 1174, E(): 3.5e-63, (42.1% identity in 539 aa overlap); P24230|RECG_ECOLI|RECG|B3652 from Escherichia coli strain K12 (693 aa), FASTA scores: opt: 457, E(): 7.3e-22, (35.2% identity in 733 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the helicase family, RECG subfamily. |
| Functional category | Information pathways |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Mutant | 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). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
