The Rep78 and Rep68 proteins of adeno-associated virus (AAV) bind to the AAV terminal repeat hairpin DNA and are required for viral replication. We have expressed a series of mutant rep genes from the human immunodeficiency virus type 1 long terminal repeat promoter in human 293 cells and in an in vitro transcription-translation system. Mutant proteins were analyzed for AAV hairpin DNA binding and AAV terminal resolution functions. Deletion of amino acid residues 523 through 621 of Rep 78 had no effect on these functions. Amber mutant Rep proteins truncated at either amino acid 237 or amino acid 243 showed no detectable hairpin DNA binding or terminal resolution activity. A frameshift mutant Rep protein which contained Rep78 amino acids 1 through 241 lacked terminal resolution functions but bound specifically to the AAV hairpin DNA. The carboxyl-terminal missense sequence in this mutant appeared to have complemented an AAV-specific DNA-binding domain within the amino terminus of the Rep protein. mutant Rep protein in which methionine 225 of Rep78 was deleted (M225dl) was reduced threefold in AAV hairpin binding and had no terminal resolution functions. A mutant Rep protein in which a glycine was substituted at position 225 (M225G) was fully functional in these assays. When M225dl extract was mixed with wild-type Rep78 extract, AAV terminal resolution by Rep78 was inhibited. These results suggest that the amino-terminal portion of Rep78 and Rep68 contains a domain which can direct binding to AAV terminal hairpin DNA and that elements within the central region of the protein stabilize binding.
