ASSEMBLY OF PROTEIN PARTICLES OF RNA BACTERIOPHAGE FR IN ABSENCE OF RNA

In absence of RNA the selfassembly of fr phage-like particles proceeds at a lower rate and a lower ionic strength than in presence of RNA. The resulting particles are similar in diameter to the empty capsids obtained by phage degradation, however, they have a higher sedimentation constant and are less penetrated by negative stain. A hypothesis for the structure of these particles is offered. © 1969.
