This paper deals with some properties of reversibly inact.**** TAA effected by means of EDTA. The mechanism of EDTA inactivation was discussed from the view point that EDTA has a conspicious suppressive effect on the reactivation of heat-inact. enzyme, while it has no effect on the active enzyme itself. Particular attention was paid to the problem of calcium transfer along with the progress of inactivation.
