A high‐speed supernatant from rat liver contains at least two latent phosphorylase phosphatases the activities of which are revealed by treatment with ethanol, urea, mercaptoethanol or trypsin. This fraction also contains at least one protein which, after heating, inhibits to various degrees the activated form(s) of the two phosphatases. The two latent enzymes can be separated by cellulose‐phosphate chromatography and can be differentiated by their preferential activation by ethanol or trypsin and by their different sensitivity to the inhibitory protein after ethanol activation.Activation of the latent phosphorylase phosphatases by ethanol, urea or mercaptoethanol is not accompanied by the destruction of the precursor of the inhibitory protein whereas activation by trypsin is. However, trypsin treatment of fractions previously activated by ethanol decreases their activity and also increases their sensitivity to the inhibitory protein in a way which is unrelated to the destruction of this inhibitor. Furthermore, some protein fractions, almost free of the precursor of the inhibitory protein can be readily activated by trypsin. It is concluded that the activation of the latent phosphorylase phosphatases is unrelated to the destruction of the inhibitory protein.
