STRUCTURE OF CYANOPHAGES AS-1L, AS-IK and S-8K V.
Summary
Structural characteristics of two strains of cyanophage AS-1, AS-1L and AS-1K, and of cyanophage S-8K are presented; these cyanophages have the same host range, but •differ in their one-step igrowth cycle and serological relationships. S-8K has an octahed¬ral head, AS-1L and AS-1K an icosahedral one. All the three cyanophages have a long, contractile tail. The size and arrangement of the head capsomeres are determined; the sheath structure of these cyanophages is supposed to be similar with that of bacteriopha-ge T4. Schematic models are given for the structure of the cyanophages. Cyanophages AS-1L, AS-1K and S-8K belong to the family Myoviridae of the genus Cyanomyovirus.
