UvrD (DNA helicase II) has been implicated in DNA replication, DNA recombination, nucleotide excision repair, and methyl-directed mismatch repair. The enzymatic function of UvrD is to translocate along a DNA strand in a 3' to 5' direction and unwind duplex DNA utilizing a DNA-dependent ATPase activity.

The structure and function of an RNA polymerase interaction domain in the PcrA/UvrD helicase: Authors: Sanders, K Lin, C-L Smith, AJ Cronin, N Fisher, G Eftychidis, V McGlynn, P Savery, NJ Wigley, DB Dillingham, MS: Item Type: Journal Article: Abstract: The structure and function of an RNA polymerase interaction domain in the PcrA/UvrD helicase Kelly Sanders, Chia Liang Lin, Abigail J. Smith , Nora Cronin, Gemma Fisher, Vasileios Eftychidis, Peter McGlynn, Nigel J. Savery , Dale B. Wigley, Mark S. Dillingham * The polarity of the helicase activity was determined to be 3'-5'. This domain is also found in subunit AddA of bacterial helicase-nuclease complex AddAB. The AddA subunit is the one responsible for the helicase activity [ (PUBMED:21071401) ]. This entry represents the ATP-binding domain found in UvrD-like and AddA helicases. GO function: This report consolidates knowledge on the new role of UvrD in filamentous phage replication, a function previously thought to be exclusive of Rep helicase.

In conclusion, our data show that the lethality in rep uvrD mutants is not a result of the overlapping functions of both helicases. UvrD, but not Rep, plays a role of RecA nucleoprotein filament remover in E. coli. The UvrD helicase proves therefore to play a new role, unrelated to DNA melting, in vivo.

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 2018-10-19 · MutL functions as a processivity factor for UvrD helicase activity.

Helicases use the energy derived from nucleoside triphosphate hydrolysis to unwind double helices in essentially every metabolic pathway involving nucleic acids. Earlier crystal structures have suggested that DNA helicases translocate along a single-stranded DNA in an inchworm fashion. We report here a series of crystal structures of the UvrD helicase complexed with DNA and ATP hydrolysis

In this study, the functional characterization of UvrD helicase from Haemophilus influenzae and Helicobacter pylori is reported. UvrD, a ubiquitous bacterial helicase that plays important roles in multiple DNA metabolic pathways, is essential for genome stability and might, therefore, be crucial in bacterial physiology and pathogenesis. In this study, the func-tional characterization of UvrD helicase from Haemophilus inﬂuenzae and Helicobacter pylori is reported. 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, translocate on single-stranded DNA as a monomer or unwind duplex DNA as a dimer.3 Therefore, the assembly state of UvrD as it pulls RNA polymerase backward is of 2012-03-09 · The Escherichia coli UvrD helicase is known to function in the mismatch repair and nucleotide excision repair pathways and has also been suggested to have roles in recombination and replication restart.
