Properties of Azotobacter phage PAV-1 and its DNA

Some properties of a phage, PAV-1, that infects both Azotobacter vinelandii strains O and OP have been examined. It contains linear, double-stranded DNA that has a molecular weight of 29 × 10 6, a sedimentation coefficient, s 20,w,Na + 0, of 33.8 S and a buoyant density in CsCl of 1.716. The phage a...

Zusammenfassung:	Some properties of a phage, PAV-1, that infects both Azotobacter vinelandii strains O and OP have been examined. It contains linear, double-stranded DNA that has a molecular weight of 29 × 10 6, a sedimentation coefficient, s 20,w,Na + 0, of 33.8 S and a buoyant density in CsCl of 1.716. The phage appears in electron micrographs to be icosahedral with a short tail surrounded by tail fibers. The virion is calculated to have a weight of about 74 × 10 6. PAV-1 is unrelated serologically to the Azotobacter phages A14, A21, A31, and A41.
