The structure and function of an RNA polymerase interaction domain in the PcrA/UvrD helicase: Authors: Sanders, K Lin, C-L Smith, AJ Cronin, N Fisher, G Eftychidis, V McGlynn, P Savery, NJ Wigley, DB Dillingham, MS: Item Type: Journal Article: Abstract:

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).

This domain is also found in subunit AddA of bacterial helicase-nuclease complex AddAB. The AddA subunit is the one responsible for the helicase activity [ (PUBMED:21071401) ].

However, there have been conflicting reports about the oligomeric state of the active helicase in vitro, some claiming that a UvrD monomer can function as a processive helicase 36,37, whereas

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.

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).

As a monomer, UvrD can translocate rapidly and proc-essively along ssDNA; however, the monomer is a poor helicase. To unwind duplex DNA in vitro, UvrD needs to be activated either by self-assembly to form a dimer or by interaction with an acces-sory protein.

Helicases are a class of enzymes vital to all organisms. their main function is to to the e. coliuvrd helicase and the bacillus stearothermophiluspcra helicase.

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. In order to achieve conditional control over NER, we generated a light-activated DNA helicase.

Inactivation of the helicase function of UvrD. To test whether the helicase function of UvrD is required for replication fork reversal, we used a previously characterized mutation in the helicase motif IV of the chromosomal uvrD gene (R284A).

Escherichia coli UvrD is a superfamily 1 DNA helicase and single-stranded DNA (ssDNA) translocase that functions in DNA repair and plasmid replication and as an anti-recombinase by removing RecA protein from ssDNA. UvrD couples ATP binding and hydrolysis to unwind double-stranded DNA and translocate along ssDNA with 3'-to-5' directionality.

To unwind duplex DNA in vitro, UvrD needs to be activated either by self-assembly to form a dimer or by interaction with an acces-sory protein. 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. In order to achieve conditional control over NER, we generated a light-activated DNA helicase. 2003-01-31 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 For the XPD helicase in eukaryotic NER a similar function in analogy to UvrB has been proposed, whereas XPB the second helicase uses only its ATPase activity during eukaryotic NER. In prokaryotic mismatch repair (MMR) UvrD again plays a central role. 2010-07-09 1997-01-17 2009-04-03 2015-04-17 However, there have been conflicting reports about the oligomeric state of the active helicase in vitro, some claiming that a UvrD monomer can function as a processive helicase 36,37, whereas In conclusion, our data show that the lethality in rep uvrD mutants is not a result of the overlapping functions of both helicases.
