General annotation
TypeCDS
FunctionInvolved in nucleotide excision repair. Has both ATPase and helicase activities. Unwinds DNA duplexes with 3' to 5' polarity with respect to the bound strand and initiates unwinding most effectively when a single-stranded region is present. Involved in the postincision events of nucleotide excision repair and methyl-directed mismatch repair.
ProductProbable ATP-dependent DNA helicase II UvrD2
CommentsRv3198c, (MTV014.42c), len: 700 aa. Probable UvrD2, ATP dependent DNA helicase II (see citation below), equivalent to P53528|UVRD_MYCLE|VRD|UVRD2|ML0637|B1937_F1_27 probable DNA helicase II homolog from Mycobacterium leprae (717 aa), FASTA scores: opt: 3749, E(): 0, (82.85% identity in 706 aa overlap); and C-terminal half (466-700 aa) corresponds to Q49764|RECQ|B1937_F2_66 putative DNA helicase RECQ (242 aa), FASTA scores: opt: 1267, E(): 1.4e-69, (82.5% identity in 234 aa overlap); products of two adjacent ORFS in Mycobacterium leprae. Also similar to other DNA helicases e.g. Q9FCK0|2SC3B6.12 from Streptomyces coelicolor (785 aa), FASTA scores: opt: 1687, E(): 1.2e-94, (52.05% identity in 728 aa overlap); P71561|CRA|IVRD|Rv0949|MT0976|MTCY10D7.25c ATP-dependent DNA helicase PCRA from Mycobacterium tuberculosis (771 aa), FASTA scores: opt: 715, E(): 1e-35, (34.1% identity in 710 aa overlap); Q9CD72|PCRA_MYCLE|UVRD|ML0153 ATP-dependent DNA helicase PCRA from Mycobacterium leprae (778 aa), FASTA scores: opt: 687, E(): 5.1e-34, (32.0% identity in 719 aa overlap); O83991|TP1028 DNA helicase II (UVRD) from Treponema pallidum (670 aa), FASTA scores: opt: 652, E(): 6e-32, (30.25% identity in 671 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the UVRD subfamily of helicases.
