Identification of additional coat-scaffolding interactions in a bacteriophage P22 mutant defective in maturation

Academic Article


  • Scaffolding proteins play a critical role in the assembly of certain viruses by directing the formation and maturation of a precursor capsid. Using electron cryomicroscopy difference mapping, we have identified an altered arrangement of a mutant scaffolding within the bacteriophage P22 procapsid. This mutant scaffolding allows us to directly visualize scaffolding density within the P22 procapsid. Based on these observations we propose a model for why the mutant prevents scaffolding release and capsid maturation.
