17 Apr 2018 An exemplary Escherichia coli helicase, UvrD, belonging to SF1, has many cellular roles such as methyl-directed mismatch repair (Iyer et al.,

2008-03-15 · The well studied E. coli UvrD helicase (helicase II) unwinds DNA in the 3' to 5' direction. Unlike many other helicases, the UvrD helicase is capable of melting fully duplex molecules (DNA fragment with blunt ends) as well as nicked circular DNA molecules.

that UvrD can pull RNA polymerase backward suggests that the role of UvrD in both NER and collision avoidance is more complex than previously thought. For helicase aficionados, the subtle aspects of UvrD mechanism are intriguing. UvrD is known to load at single-stranded/ double-stranded junctions and, depending on its oligmeric state In an effort to improve the specificity and performance of HDA, we have cloned and purified a thermostable UvrD helicase (Tte-UvrD) and the mutL homolog (Tte-MutL) from Thermoanaerobacter tengcongensis. Characterization of the Tte-UvrD helicase shows that it is stable and active from 45 to 65 degrees C. View protein in PROSITE PS51198, UVRD_HELICASE_ATP_BIND, 1 hit PS51217, UVRD_HELICASE_CTER,

UvrD monomers can translocate along single-stranded DNA, but self-assembly or interaction with an accessory factor is required to activate processive DNA unwinding in vitro. UvrD is a helicase that is widely conserved in gram-negative bacteria. A uvrD homologue was identified in Mycobacterium tuberculosis on the basis of the homology of its encoded protein with Escherichia coli UvrD, with which it shares 39% amino acid identity, distributed throughout the protein. UvrD helicase activity can be activated through interactions with the MutL protein (34, 35) that is required for methyl-directed mismatch repair (36).

EMBO J. 24 , 180–189 (2005).

UvrD helicase is a component of MMR complex and plays an essential role in the DNA repair by providing the unwinding function. In the present manuscript we present an in silico analysis of UvrD helicase from two plant species (Arabidopsis and rice).

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. The most known Helicases in the SF1B group are RecD and Dda helicases.

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.

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.

This section displays by default the canonical protein sequence and upon request all isoforms described in the entry. 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.

In the presence of 10 ng Tte UvrD Helicase (right), the positive reaction maintains its rapid amplification time with a slight reduction in total RFU, while the NTC reaction is completely suppressed. 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).
