title: Cloning a replication function from the streptomycete bacteriophage FP43.
abstract: Streptomyces griseofuscus cells carrying a 4.4-kb SphI DNA fragment from bacteriophage FP43 inhibited plaque formation (Pin) by FP43, and the Pin function was localized to a 0.96-kb SacII fragment. The same 4.4-kb SphI fragment was able to replicate freely in several streptomycetes, including S. griseofuscus, and the replication (Rep) function was localized to a 1.2-kb SphI-FspI fragment. Plasmids with FP43 Rep function are unstable and are present at about 20-50 copies per chromosome. Plasmids with FP43 Rep function are compatible with SCP2* plasmids.
