Tte UvrD Helicase is a repair helicase capable of unwinding double-stranded DNA, without a requirement for a specific flap or overhang structure, from the thermophilic organism Thermoanaerobacter tengcongensis.It is active on a wide range of DNA substrates and, along with its thermostability (active to 70°C), Tte UvrD Helicase has been demonstrated to be a useful additive for improving

It is involved in the post-incision events of nucleotide excision repair and methyl-directed mismatch repair. It unwinds DNA duplexes with 3'-5' polarity with respect to the bound strand and initiates unwinding most effectively when a single-stranded region is present. 2009-04-03 · UvrD is an abundant helicase in Escherichia coli with well characterized functions in mismatch and nucleotide excision repair and a possible role in displacement of proteins such as RecA from single-stranded DNA. UvrD, a ubiquitous bacterial helicase that plays important roles in multiple DNA metabolic pathways, is essential for genome stability and might, therefore, be crucial in bacterial physiology and pathogenesis. In this study, the func-tional characterization of UvrD helicase from Haemophilus inﬂuenzae and Helicobacter pylori is reported. Veaute, X. et al.

It was reported previously that MLH (or Finally, the UvrD helicase then unwinds DNA so the damaged segment is removed.

Bacterial UvrD helicase. It is involved in the post-incision events of nucleotide excision repair and methyl-directed mismatch repair. It unwinds DNA duplexes with 3'-5' polarity with respect to the bound strand and initiates unwinding most effectively when a single-stranded region is present.

UvrD helicase activity can be activated through interactions with the MutL protein (34, 35) that is required for methyl-directed mismatch repair (36). We have shown that a single MutL dimer is sufficient to activate the UvrD monomer helicase and increase its processivity as well as stimulate the UvrD dimer helicase (37). The most known SF1A helicases are Rep and UvrD in gram-negative bacteria and PcrA helicase from gram-positive bacteria.

Background: The ability of UvrD, a DNA helicase, to unwind a Holliday junction has not been directly tested. Results: UvrD catalyzed robust unwinding of a Holliday junction producing a forked structure. Conclusion: UvrD unwinds a Holliday junction by binding to the junction and translocating along opposite arms. UvrD, a highly conserved helicase involved in mismatch repair, nucleotide excision repair (NER), and recombinational repair, plays a critical role in maintaining genomic stability and facilitating DNA lesion repair in many prokaryotic species.

Characterization of the Tte-UvrD helicase shows that it is stable and active from 45 to 65 degrees C. We have found that the Tte-UvrD helicase unwinds blunt-ended DNA duplexes as well as substrates possessing 3'- or 5'-ssDNA tails. 1988-04-01 · CPX-5542, MutL-UvrD DNA helicase complex: DIP i: DIP-11103N: IntAct i: P03018, 39 interactors: STRING i: 511145.b3813 We report here a series of crystal structures of the UvrD helicase complexed with DNA and ATP hydrolysis intermediates. These structures reveal that ATP binding alone leads to unwinding of 1 base pair by directional rotation and translation of the DNA duplex, and ADP and Pi release leads to translocation of the developing single strand. UvrD had already been found to remove proteins from DNA, but always in a situation coupled with DNA unwinding: in the context of UvrABC‐dependent UV repair, after the incision step mediated by UvrABC, the UvrD helicase was found to remove both the 12‐mer containing the lesion and the UvrC protein (Orren et al, 1992). UvrD helicase plays essential roles in multiple DNA metabolic processes, including methyl-directed mismatch repair.
