WebApr 20, 2012 · Clamp loaders are pentameric ATPases of the AAA+ family that operate to ensure processive DNA replication. The helicase is a homohexamer that encircles the lagging strand and binds directly to the primase synthesizing the primer RNA. Further hydrolysis events cause release of the clamp loader from the clamp and DNA, resulting …
