DnaC helicase loader (DnaC) transfers helicase to replication origins. The helicase loaders belong to two classes. The ‘ring breakers’ break the hexameric helicase to allow the DNA to pass through. The ‘ring makers’ assemble the helicase monomers to hexamers around the DNA.
For the theoretical model structure of E. coli DnaC see Structure of E. coli DnaC helicase loader.
