Gene Rv1633
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in nucleotide excision repair. The ABC excision nuclease is a DNA repair enzyme that catalyzes the excision reaction of UV-damaged nucleotide segments producing oligomers having the modified base(S). UVRB stimulates the ATPase activity of UVRA in the presence of UV-irradiated double-stranded DNA. It also enhances the ability of UVRA to bind to UV-irradiated duplex DNA |
| Product | Probable excinuclease ABC (subunit B - helicase) UvrB |
| Comments | Rv1633, (MTCY01B2.25), len: 698 aa. Probable uvrB, excinuclease ABC, subunit B; helicase (see Mizrahi & Andersen 1998; Sancar 1994); has ATP/GTP-binding site motif A (P-loop; PS00017) near N-terminus (see citation below). FASTA best: UVRB_MICLU|P10125 from Micrococcus luteus (709 aa), opt: 3268, E(): 0, (71.3% identity in 704 aa overlap). Also similar to Mycobacterium tuberculosis Rv2973c (recG); and Rv1020 (mfd). Belongs to the UVRB family. |
| Functional category | Information pathways |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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). |
| Transcriptomics | mRNA supposedly identified by SCOTS method, 48h after infection of cultured human primary macrophages (see Graham & Clark-Curtiss 1999). |
| 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). Transposon mutant is hypersensitive to acidified nitrite (See Darwin et al., 2003).
