Bacteriophage SPO1 structure and morphogenesis. II. Head structure and DNA size

Abstract

The capsid of bacteriophage SPO1 is icosahedral, and the subunit arrangement on the 87-nm-diameter head suggests the triangulation number T = 16. The major capsid protein (45,700 daltons) is cleaved from a 47,700-dalton precursor. Tubular heads (polyheads) are produced by mutations in genes 5 and 8 and contain cores as well as capped ends. The lattice constant of these structures is 13.4 nm; diameter is 109.5 nm. The size of the double-stranded SPO1 DNA (containing 5' hydroxymethyl uracil in place of thymine) was measured by sedimentation analysis and electron microscopy and has a molecular weight of 86 X 10(6) (about 140 kilobase pairs), which is smaller than several previously reported values.
