E. coli
UvrD is a DNA helicase that uses the energy generated
by the hydrolysis of nucleoside triphosphates to break the hydrogen
bonds linking the two strands together in duplex DNA. It is active
at 37?C.

1X Helicase Buffer M:
10 mM Dithiolthreitol
10 mM Magnesium Acetate
35 mM Tris-Acetate pH 7.5 @ 25°C
3 mM ATP.
Incubate at 37?C.
Notes:
E.coli UvrD helicase may require MutL and/or SSB for optimal
performance in specific applications.
: MutL stimulates UvrD helicase activity more than tenfold by lo

: MutL and SSB are required in Helicase-Dependent Amplification
using E. coli UvrD (Myriam Vincent, Yan Xu, and Huimin Kong (2004)
EMBO reports Vol. 5, 795 - 800).
