Yuji Tonomura: a pioneer in the field of energy transduction in muscle contraction.
Late Professor Yuji Tonomura has made a great contribution in the study of energy transduction in muscle contraction. He was the investigator who first proposed that a myosin-phosphate intermediate is produced subsequently to the Michaelis-Menten complex in the pre-steady state of the myosin ATPase reaction and that it is a key intermediate for muscle contraction. Here, his proposed intermediate will be viewed from the prospective of today's understanding of actomyosin ATPase kinetics and in the context of myosin motor domain crystal structures.
