anti-E.coli RuvB antibody, rabbit serum


SKU: 61-007 Research Area: Applications:


E.coli RuvB protein forms a complex with RuvA protein and the complex promotes branch migration of Holliday junction at the late stage of homologous recombination and recombination repair. RuvB is a DNA motor protein which possesses the ATPase activity, activated by DNA and RuvA protein (1, 2). Its molecular weight is 37kD.
