Replication of phage G4. A novel and simple system for the initiation of deoxyribonucleic acid synthesis.


Conversion in vitro of single-stranded circular DNA of phage G4 (related to phage phiX174) to the double-stranded replicative form (RF-II) depends on a novel and relatively simple group of three proteins: a priming protein of approximately 65,000 daltons, the DNA unwinding protein, and the DNA polymerase III holoenzyme. Stimulation by ATP and GTP suggests… (More)
