Helicase–primase complex

A helicase–primase complex (also helicase-primase, Hel/Prim, H-P or H/P) is a complex of enzymes including DNA helicase and DNA primase. A helicase-primase associated factor protein may also be present.[1]

The complex is used by herpesviruses in which it is responsible for lytic DNA virus replication.[2][3][4] In many dsDNA viruses primase and helicase are fused into a single polypeptide, so that the primase and helicase domains correspond to the N-terminal and C-terminal parts of the protein, respectively.[5] A helicase-primase inhibitor (HPI) is a drug that blocks this action through acting as an enzyme inhibitor.
