Parker, ML and Eiserling, FA (1983) Bacteriophage SPO1 structure and morphogenesis. III. SPO1 proteins and synthesis. J. Virol. 46:260-9


The virion proteins of SPO1 have been determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis methods on purified phage components and on phage lysates. The phage head contains 16 proteins, and the connector or neck structure has an additional 3 proteins not found in the head. The proximal part of the tail, composed of sheath, tube and connecting components, contains six proteins. The distal baseplate is the most complex structure, with 28 proteins identifiable on sodium dodecyl sulfate gels. The maximum number of proteins found in phage subassemblies is 53, which would account for nearly half the coding capacity of the SPO1 genome.
