Summary

Go to the top of the page Help

Official Symbol: uvrD
Official Full Name: DNA helicase II
Primary source: ECOCYC:EG11064
Locus tag: b3813
See related: ASAP:ABE-0012455
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage: Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as: dar-2; dda; ECK3808; mutU; pdeB; rad; recL; srjC; uvr502; uvrE
Summary: The completion of nucleotide excision repair depends upon the release of the oligonucleotide fragment along with the UvrB and UvrC proteins which are then able to be recycled to undertake another excision repair event. [More information is available at EcoCyc: EG11064].

Recipient UvrD helicase is involved in single- to double-stranded DNA conversion during conjugative plasmid transfer.
Title: Recipient UvrD helicase is involved in single- to double-stranded DNA conversion during conjugative plasmid transfer.
MutL Escherichia coli
Title: UvrD helicase activation by MutL involves rotation of its 2B subdomain.
Observations are consistent with an exonuclease-independent MMR strand excision mechanism that relies on EcMutL-EcUvrD helicase-driven displacement of ssDNA segments between adjacent EcMutH-GATC incisions.
Title: MutL sliding clamps coordinate exonuclease-independent Escherichia coli mismatch repair.
Rep and UvrD helicases operate on DNA at the replication fork whereas DinG helicase acts via a different mechanism
Title: Direct removal of RNA polymerase barriers to replication by accessory replicative helicases.
The lowest free-energy path shows that UvrD opens the interface between two domains, allowing the bound ssDNA to escape. The simulation results predict a key metastable 'tilted' state during ssDNA strand switching.
Title: Free-energy simulations reveal molecular mechanism for functional switch of a DNA helicase.
Large domain movements upon UvrD dimerization and helicase activation has been reported.
Title: Large domain movements upon UvrD dimerization and helicase activation.
Results show that UvrD monomer translocation rate depends on the single-stranded DNA base composition, even in the absence of any predicted basepairing within the nucleic acid. Translocation is faster on single-stranded DNA-containing pyrimidines and slower on ssDNA-containing purines
Title: Modulation of Escherichia coli UvrD Single-Stranded DNA Translocation by DNA Base Composition.
these data reveal that UvrD exhibits two distinct types of unwinding activity regulated by its stoichiometry. Furthermore, two UvrD conformational states, termed "closed" and "open," correlate with movement toward or away from the DNA fork.
Title: Protein structure. Direct observation of structure-function relationship in a nucleic acid-processing enzyme.
The unwinding processivity is increased in the UvrD303 mutant.
Title: The UvrD303 hyper-helicase exhibits increased processivity.
it is hypothesized that recA4162 suppresses SOS expression best when the ssDNA occurs at a gap and that uvrD303 is able to decrease SOS expression when the ssDNA is either at a gap or when it is generated at a DSB but does so better at a gap
Title: Specificity in suppression of SOS expression by recA4162 and uvrD303.
