RecQ helicases catalyze double-stranded DNA unwinding in the 3’ to 5’ direction, which is driven by ATPase activity that is dependent on a bivalent cation (1). RecQ helicases are important in coordinating genome maintenance and preserving genomic integrity in prokaryotes and eukaryotes (2). E. coli RecQ plays an important role in resuming DNA replication at stalled replication forks after repairing UV-induced DNA damage (3). They are also important in preventing future chromosomal abnormalities that result from DNA damage (3).
