New research shows that the nuclease domain of the E. coli RecBCD helicase plays a key role in regulating DNA binding and the extent of base pair melting during double-strand break repair. Deleting ...
In this issue, Wu et al. show that the RecBC helicase, which is involved in repairing double-strand DNA breaks, uses one ATPase motor to drive two translocases along opposite strands of DNA—much as an ...
