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.

Rep and UvrD are two related Escherichia coli helicases, and inactivating both is lethal. Based on the observation that the synthetic lethality of rep and uvrD inactivation is suppressed in the absence of the recombination presynaptic proteins RecF, RecO, or RecR, it was proposed that UvrD is essential in the rep mutant to counteract a deleterious RecFOR-dependent RecA binding.

The Rep family helicases are composed of four structural domains. The Rep family function as dimers.

UvrD is a DNA helicase that participates in nucleotide excision repair and several replication-associated processes, including methyl-directed mismatch repair and recombination. 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. Our previous studies have We have shown that the uvrD gene product, previously identified in maxicell extracts as a 73 kilodalton protein, copurifies with single stranded DNA-dependent ATPase and ATP-dependent DNA helicase activities. This protein is specifically precipitated from maxicell extracts by antibodies raised again … UvrD has a critical role in the processing of DNA-protein cross-links After replication blockage by an inverted rrn, Rep in conjunction with DinG or UvrD removes RNA polymerase, a task that is fulfilled in its absence by the SOS-induced DinG and UvrD helicases.

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 UvrD may refer to: UvrABC endonuclease, an enzyme DNA helicase, an enzyme class ‹ The template below (Disambiguation) is being considered for merging. Tte-UvrD was used to develop athermophilichelicase-dependent amplification (tHDA) system to selectively amplify target sequences at 60-65 degrees C. The tHDA system is more efficient than mHDA, displaying heightened amplification sensitivity without the need for the MutL and SSB accessory proteins. Tte UvrD Helicase is a repair helicase capable of unwinding double-stranded DNA, without a requirement for a specific flap or overhang structure, from the thermophilic organism Thermoanaerobacter tengcongensis. 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.

DNA helicases are enzymes capable of unwinding double-stranded DNA (dsDNA) to provide the single-stranded DNA template required in many biological processes. Among these, UvrD, an essential DNA repair enzyme, has been shown to unwind dsDNA while moving 3′-5′ on one strand.

These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists.

Crystal structures of several uvrD-like DNA helicases have been solved [ PUBMED:9288744, PUBMED:10199404, PUBMED:15538360].

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
