A considerable number of substances have been studied as possible activators for papain. These studies led to the development of theories on the mode of action of these activators. As we found sodium thiosulfate to be a potent activator for papain and especially suitable for the study of the activation reaction, we shall present here some of our results. Moreover, thiosulfate may have some practical interest in connection with the industrial and medical use of papain.
