Abstract
The replication initiator protein E1 binds to the origin of replication of bovine papillomavirus in several forms. E1 can bind to its recognition sequence as a monomer together with the viral transcription factor E2, or as a trimeric E1 complex. The trimerization of E1 is mediated by the sequence-specific binding of E1 to DNA, and results in an E1 complex that is linked topologically to the DNA because the three molecules of E1 form a ring-like structure that encircles the DNA. These results demonstrate that E1 utilizes unusual mechanisms for sequence-specific binding to DNA and for the generation of a structure that encircles the DNA. We believe that these forms of E1 bound to the origin of replication represent intermediates in a transition in the function of E1, from a sequence-specific origin of replication recognition protein to a form of E1 that is competent for the initiation of viral DNA replication.
