| Abstract: | The Group B Staphylococcus phage P11-M15 is shown to be 51% protein and 49% deoxyribonucleic acid (DNA). The intact virion has a molecular weight of 66.7 x 10(6) daltons. The purified viral DNA has a molecular weight of 32.7 x 10(6) daltons. The intact virion is shown to be composed of a polyhedral head which is attached at one of its vertices to a flexible tail having helical symmetry. The tail structure is terminated by a complex baseplate which has sixfold symmetry. The virion contains a single molecule of double-stranded DNA which has no apparent single-strand nicks or single-stranded terminal redundancies. |
