Gene Rv0861c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in nucleotide excision repair. Has ATP-dependent 3' -> 5'helicase activity: acts by opening DNA either around the RNA transcription start site or the DNA damage. |
| Product | DNA helicase Ercc3 |
| Comments | Rv0861c, (MTV043.54c), len: 542 aa. Ercc3, DNA helicase (see citation below), equivalent to NP_302420.1|NC_002677 probable DNA helicase from Mycobacterium leprae (549 aa). Also highly similar to others (shorter than several eukaryotic enzymes) e.g. NP_218820.1|NC_000919|AE001217|AE0 01217_6 putative DNA repair helicase from Treponema pallidum (606 aa), FASTA scores: opt: 1275, E(): 0, (47.5% identity in 592 aa overlap); Q00578|RA25_YEAST DNA repair helicase from Saccharomyces cerevisiae (843 aa), FASTA scores: opt: 777, E(): 0, (30.4% identity in 605 aa overlap); P49135|XPB_MOUSE DNA-repair protein complementing XP-B cells from Mus musculus (Mouse) (783 aa), FASTA scores: opt: 761, E(): 0, (36.3% identity in 375 aa overlap); etc. Seems to belong to the helicase family. Alternative nucleotide at position 958922 (C->a; A410A) has been observed. |
