Escherichia coli UvrD protein is a 3′ to 5′ SF1 helicase required for DNA repair as well as DNA replication of certain plasmids. We have shown previously that

• Acting alongside RecF, RecX suppresses DNA degradation and stimulates gamma-survival. • RecN suppresses DNA degradation, acting in the RecABCD pathway. • A uvrD − phenotype is characterized by an increased rate of recombination and by a constitutive induction of the SOS response , which controls expression of a number of DNA repair genes under the control of the LexA transcriptional regulator . 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. *Attention* - We have re-recorded the audio and re-created this video.

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. 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 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. 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.

2012-05-09 · UvrD monomer binding to ssDNA occurs randomly, so after the UvrD:ssDNA complex formed, it was mixed with buffer T 20, ATP, MgCl 2, and heparin. Once the UvrD monomer reached the Cy3-labeled and fluorescein-labeled 5’-ends of the ssDNA, the fluorescence intensity was enhanced and quenched, respectively.

UvrD is a DNA helicase involved in several DNA repair pathways. We report here crystal structures of Deinococcus radiodurans UvrD (drUvrD) in complex with DNA in different nucleotide-free and bound states. These structures provide us with three distinct snapshots of drUvrD in action and for the 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. Tte UvrD Helicase: M1202: 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. Tth Argonaute: M0665 Moreover, the two distinct activities correlate with the number of UvrD helicases present on the DNA hairpin, measured by counting singly labeled UvrD .

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.

UvrD-like DNA helicases belong to SF1, but they differ from classical SF1/SF2 (see ) by a large insertion in each domain. UvrD-like DNA helicases unwind DNA with a 3'-5' polarity . Crystal structures of several uvrD-like DNA helicases have been solved (see for example ) [4,5,6].

We report here crystal structures of Deinococcus radiodurans UvrD (drUvrD) in Oct 19, 2018 UvrD protein can self-associate into dimers and tetramers [11], and its assembly state regulates its properties. A UvrD monomer can processively UvrD/REP helicase N-terminal domain Provide feedback. The Rep family helicases are composed of four structural domains. The Rep family function as dimers.
