Accession IDs, EG11064 (EcoCyc) b3813. ECK3808 P03018 (UniProt), Length, 2163 bp / 720 Oct 15, 2013 UvrD is a DNA helicase involved in several DNA repair pathways. 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.

• 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.

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.

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. The results directly demonstrate that the UvrD monomer is a highly processive single-stranded DNA translocase that is stopped by a double-stranded DNA, whereas two monomers are required to unwind 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).

The kinetic mechanism by which the DNA repair helicase UvrD of Escherichia coli unwinds duplex DNA was examined with the use of a series of oligodeoxynucleotides with duplex regions ranging from 10 to 40 base pairs.

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. 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.

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 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.
