The degrees of turbidity and light scattering intensity decreased with increasing the urea concentration on heating from 20 to 80°C, compared with myosin B in the absence of urea. These phenomena suggested that the aggregation process of myosin B was inhibited by thepresence of urea. The surface sulfhydryl groups of myosin B were oxidized readily by heating myosin B in the presence of urea. 8-Anilino-1-naphthalenesulfonate fluorescence intensity indicated that the amount of hydrophobic group decreased with the increase of the oxidized SH group. These results suggested that the configuration of myosin B molecule consequently changed to be compact within a single myosin B on the treatment of urea and heating.}, pages = {103--109}, title = {Thermal Denaturation of Myosin B in the Presence of Urea}, volume = {40}, year = {} }
