The genome of Bacillus subtilis bacteriophage SPP1, a linear, 28.5-megadalton DNA duplex, was mapped by analysis with the restriction endonucleases endo R.Sal I, Sma I, Xba I, Bgl I, Bgl II, and EcoRI. The SPP1 genome, like that of the Salmonella typhimurium phage, P22, was found to be a terminally repetitious, circularly permuted molecule.
6-(p-Hydroxyphenylazo)uracil
, a selective, reversible inhibitor of SPP1 DNA synthesis, was exploited to synchronize the initiation of genome replication and to selectively label the site of its initiation with radioactive thymidine. Restriction
endonuclease
analysis of the distribution of the label located the origin of replicative synthesis at an area approximately 0.2 genome length from one molecular terminus.
