In 1972, he and his co-workers, by taking into account the spatial factor and force field factor between the enzyme and its substrate, reported that the upper limit of diffusion-controlled reaction of enzyme or diffusion limited enzyme is one order of magnitude higher than the conventional estimation, and can be used to elucidate some surprisingly high reaction rates in molecular biology.
