UvrD exhibits modest processivity as a DNA helicase (40–50 bp) (53– 55) making this protein an interesting choice for the helicase responsible for the unwinding event in MMR. UvrD is also the helicase responsible for the unwinding event associated with excision repair ( 56 – 59 ), which requires unwinding of a short 12–13 base long oligonucleotide well within the limits of the processivity of UvrD.

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 In an effort to improve the specificity and performance of HDA, we have cloned and purified a thermostable UvrD helicase (Tte-UvrD) and the mutL homolog (Tte-MutL) from Thermoanaerobacter tengcongensis. Characterization of the Tte-UvrD helicase shows that it is stable and active from 45 to 65 degrees C. View protein in PROSITE PS51198, UVRD_HELICASE_ATP_BIND, 1 hit PS51217, UVRD_HELICASE_CTER,

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 is a helicase that is widely conserved in gram-negative bacteria. A uvrD homologue was identified in Mycobacterium tuberculosis on the basis of the homology of its encoded protein with Escherichia coli UvrD, with which it shares 39% amino acid identity, distributed throughout the protein. UvrD helicase activity can be activated through interactions with the MutL protein (34, 35) that is required for methyl-directed mismatch repair (36). We have shown that a single MutL dimer is sufficient to activate the UvrD monomer helicase and increase its processivity as well as stimulate the UvrD dimer helicase (37).
