Uvrd helicase function

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 helicase/translocase that functions in DNA repair, replication, and recombination. Although a UvrD monomer can translocate along single-stranded DNA, self 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 functional characterization of UvrD helicase from Haemophilus influenzae and Helicobacter pylori is reported. Abstract. The PcrA/UvrD helicase functions in multiple pathways that promote bacterial genome stability including the suppression of conflicts between replication and transcription and facilitating the repair of transcribed DNA. 2012-05-09 · Translocation of UvrD. UvrD is a helicase and translocase that functions in excision repair to remove the damaged segment of DNA so that DNA polymerase can fill in the gap.

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

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. The PcrA/UvrD helicase functions in multiple path-ways that promote bacterial genome stability includ-ing the suppression of conﬂicts between replication and transcription and facilitating the repair of tran-scribed DNA. The reported ability of PcrA/UvrD to bind and backtrack RNA polymerase (1,2) might be Escherichia coli UvrD DNA helicase functions in several DNA repair processes. 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. 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.
