General annotation
TypeCDS
FunctionInvolved 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.
ProductDNA helicase Ercc3
CommentsRv0861c, (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.
Functional categoryInformation pathways
ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cell wall and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005).
MutantNon-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).
