uvrD homolog has been shown to partially compensate for the repair function of E. coli UvrD, suggesting that the function of the helicase is evolutionarily conserved (11). Characterization of this protein indicates that the T. thermophilus UvrD pos-sesses a 3-5 DNA helicase activity similar to the E. coli UvrD (12). UvrD helicase plays essential roles in multiple DNA metabolic processes, including methyl-directed mismatch repair. 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. 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 specificity of isothermal amplification reactions, particularly in conjunction with the WarmStart® LAMP Kit (DNA & RNA).

Escherichia coli UvrD is a non-hexameric SF1 helicase and ssDNA translocase that functions in methyl-directed mismatch repair7 and nucleotide excision repair8 of DNA, reversal of replication forks9,10 and replication of some plasmids.11 UvrD also functions to remove proteins from DNA12,13 and as an anti-recombinase by displacing RecA Feb 4, 2017 Abstract. The PcrA/UvrD helicase functions in multiple pathways that promote bacterial genome stability including the suppression of conflicts Apr 17, 2018 An exemplary Escherichia coli helicase, UvrD, belonging to SF1, has many cellular roles such as methyl-directed mismatch repair (Iyer et al., This stimulation likely plays a role in DNA strand and protein displacement by UvrD in nucleotide excision repair.

In this study, the func-tional characterization of UvrD helicase from Haemophilus inﬂuenzae and Helicobacter pylori is reported. 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, translocate on single-stranded DNA as a monomer or unwind duplex DNA as a dimer.3 Therefore, the assembly state of UvrD as it pulls RNA polymerase backward is of 2012-03-09 · The Escherichia coli UvrD helicase is known to function in the mismatch repair and nucleotide excision repair pathways and has also been suggested to have roles in recombination and replication restart. The primary intermediate DNA structure in these two processes is the Holliday junction.

In addition, UvrD interacts with many other UvrD is a DNA helicase that participates in nucleotide excision repair and several replication-associated processes, including methyl-directed mismatch repair and recombination. UvrD is capable of displacing oligonucleotides from synthetic forked DNA structures in vitro and is essential for viability in the absence of Rep, a helicase associated with processing replication forks. UvrD, a member of the helicase SF1 superfamily, plays an essential role in bacterial NER by unwinding the duplex DNA in the 3' to 5' direction to displace the lesion-containing strand.

Workflow. Helicases are a class of enzymes vital to all organisms. Their main function is to unpack an organism's genes. They are motor proteins that move directionally along a nucleic acid phosphodiester backbone, separating two annealed nucleic acid strands such as DNA and RNA (hence helic- + -ase), using energy from ATP hydrolysis.
