UvrD helicase is essential for Tus removal during recombination-dependent replication restart from Ter sites. Data show that UvrD, but not Rep, directly prevents homologous recombination in vivo, and that RecA contributes to toxicity in the rep uvrD mutant. Role of UvrD on RecET-mediated illegitimate recombination. 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. The Rep helicase is needed during bacteriophages M13 and ΦX174 replication (Takahashi et al, 1979), the UvrD helicase ensures the replication of Gram‐negative rolling‐circle plasmids (Bruand and Ehrlich, 2000) and the PcrA helicase ensures the replication of Gram‐positive rolling‐circle plasmids (Petit et al, 1998; Anand et al, 2004). Characterization of a Thermostable UvrD Helicase and Its Participation in Helicase-dependent Amplification* Helicase-dependent amplification (HDA) is an isothermal in vitro DNA amplification method based upon the coordinated actions of helicases to separate double-stranded DNA and DNA polymerases to synthesize DNA. UvrD is a superfamily I DNA helicase with well documented roles in excision repair and methyl-directed mismatch repair (MMR) in addition to poorly understood roles in replication and recombination.

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-RNA polymerase interactions are governed by UvrD's carboxy-terminal Tudor domain. Coronavirus: Find the latest articles and preprints Sign in or create an account 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 Tte-UvrD Helicase.

This ability of UvrD to remodel RNAP-DNA complexes might also be relevant to the ability of PcrA/UvrD to suppress conflicts between replication and transcription, a property it shares with the very closely related helicase Rep (although Rep does not interact with RNAP) (26– 28).

2006-12-29 · UvrD, originally known as DNA helicase II in E. coli (Hickson et al., 1983), is the founding member of SF1 and unwinds DNA in the 3′→ 5′ direction (Matson and George, 1987). The kinetic mechanism by which the DNA repair helicase UvrD of Escherichia coli unwinds duplex DNA was examined with the use of a series of oligodeoxynucleotides with duplex regions ranging from 10 to 40 base pairs. Single-turnover unwinding experiments showed distinct lag phases that increased with duplex length because partially unwound DNA intermediate states are highly populated during UvrD exhibits modest processivity as a DNA helicase (40–50 bp) (53– 55) making this protein an interesting choice for the helicase responsible for the unwinding event in MMR. UvrD is also the helicase responsible for the unwinding event associated with excision repair ( 56 – 59 ), which requires unwinding of a short 12–13 base long oligonucleotide well within the limits of the processivity of UvrD. 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.
