Function
function
The main replicative DNA helicase, it participates in initiation and elongation during chromosome replication. Travels ahead of the DNA replisome, separating dsDNA into templates for DNA synthesis. A processive ATP-dependent 5'-3' DNA helicase it has DNA-dependent ATPase activity.
Catalytic activity
- ATP + H2O = ADP + phosphate + H+
- Couples ATP hydrolysis with the unwinding of duplex DNA at the replication fork by translocating in the 5'-3' direction. This creates two antiparallel DNA single strands (ssDNA). The leading ssDNA polymer is the template for DNA polymerase III holoenzyme which synthesizes a continuous strand.
