It was found that the absorption spectrum of beta-naphthyl triphosphate is different from that of beta-naphthyl diphosphate in the range 290-335 nm. Thus, beta-naphthyl triphosphate hydrolysis by heavy meromyosin can be recorded continuously as a function of time by means of a spectrophotometer. By analyzing the time course, the apparent kinetic parameters were easily and rapidly obtained. If necessary, the true kinetic parameters, including the product dissociation constants, can be estimated spectrophotometrically. Beta-Naphthyl triphosphate hydrolysis was inhibited competitively by ATP. By analyzing the time course, it was, therefore, possible to estimate the kinetic parameters of ATP hydrolysis indirectly, and resonable values were obtained. Beta-Naphthyl triphosphate hydrolysis by heavy meromyosin was performed under various conditions. Unlike that of ATP, the hydrolysis of beta-naphthyl triphosphate was inhibited monotonously by treatment of heavy meromyosin with p-hydroxymercuribenzoate.
