The mismatch repair protein MutL is known to stimulate UvrD. 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.

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

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. The gene was cloned, and a histidine-tagged form of the protein was expressed and purified to

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.

1988-04-01 · Strongly sensitive to UV, ciprofloxacin (CFX), and azidothymidine (AZT) in single deletion mutants, radA-uvrD double deletions are more sensitive yet. Adding recF mutations almost completely suppresses AZT and partially suppresses UV and CFX sensitivity, suggesting RadA processes a class of intermediates that accumulate in uvrD mutants (PubMed: 25484163 ). 1 Publication

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.

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. 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 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 helicase/translocase that functions in DNA repair, replication, and recombination.

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. 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- assembly or interaction with an accessory protein is needed to activate its helicase activity in vitro. 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. 2020-10-23 · UvrD, also termed Helicase II, binds directly to RNAP and is proposed to function within the TCR by using its inherent ATPase activity for backtracking the stalled RNAP without displacing it Bacterial UvrD helicase. 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. Helicases use the energy derived from nucleoside triphosphate hydrolysis to unwind double helices in essentially every metabolic pathway involving nucleic acids.
