Most of it started with T4 phage and was then taken over.

Professor Fumio Arisaka is one of the famous leaders in bacteriophage research, especially in the areas of protein biophysics and structural biology. Autonomous phage morphogenesis is a self-assembly process controlled by subunit-subunit interaction. Under this principle, Fumio has studied T4 tail assembly and morphology. He has also contributed structural information about T4 phage through a combination of X-ray structural analysis and three-dimensional image reconstruction using cryo-electron microscopy. Most of the development of ultracentrifugation applications for molecular assembly and phage morphogenesis research was also performed in Fumio's laboratory. Fumio is a pioneer of supramolecular protein assembly study, and his science continues in the research work of the approximately 150 people who had attended his final lecture at the Tokyo Institute of Technology.
