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.

Therefore, in order for UvrD to unwind toward the mismatch it must be loaded onto the appropriate strand to unwind with its known polarity. If MutL functions to load UvrD on the DNA, this provides a mechanism to load UvrD exclusively on the appropriate strand. 2008-03-15 · UvrD from E. coli is a 73-kDa protein and was characterized as DNA helicase II (Kumura and Sekiguchi, 1984). UvrD and Rep belong to the SF1 family, which shares 40% amino-acid identity and these are remarkably similar to the PcrA helicase of Gram-positive bacteria. The uvrD gene of E. coli encodes a DNA-dependent ATPase. Nature 298:98-100; Arthur, H.M., P.B. Eastlake 1983. Transcriptional control of the uvrD gene of Escherichia coli.

Dec 29, 2006 UvrD Helicase Unwinds DNA One Base Pair at a Time by a Two-Part Power Stroke · Summary. Helicases use the energy derived from nucleoside Synonyms, uvr502; srjC; uvrE; dar-2; dda; mutU; pdeB; rad; recL. 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.

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

• 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 .

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).

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 .

1 Publication aspects of UvrD mechanism are intriguing.

Pre-steady-state chemical quenched-flow techniques were used to study DNA unwinding catalyzed by Escherichia coli UvrD helicase (helicase II), a member of the SF1 helicase superfamily. DNA helicase II (sometimes called UvrD) then comes in and removes the excised segment by removing the base pairing. The UvrB still remains in place even though UvrC has disassociated at this stage, as UvrB may be involved to prevent the reannealing of the excised DNA. 2018-05-01 · RecF and UvrD proteins suppress DNA degradation and promote E. coli gamma-survival. • RecF and UvrD act in one pathway, which depends on RecA protein and SOS induction. • Acting alongside RecF, RecX suppresses DNA degradation and stimulates gamma-survival.

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.

UvrD-like DNA helicases belong to SF1, but they differ from classical SF1/SF2 by a large insertion in each domain. UvrD-like DNA helicases unwind DNA with a 3'-5' polarity [ PUBMED:10679457]. Crystal structures of several uvrD-like DNA helicases have been solved [ PUBMED:9288744, PUBMED:10199404, PUBMED:15538360].

An oligomeric form of E. coli UvrD is required for optimal helicase activity. Pre-steady-state chemical quenched-flow techniques were used to study DNA unwinding catalyzed by Escherichia coli UvrD helicase (helicase II), a member of the SF1 helicase superfamily. DNA helicase II (sometimes called UvrD) then comes in and removes the excised segment by removing the base pairing.
