Abstract
SOLUTIONS of takadiastase (Parke, Davis and Co., Ltd.) split casein, gelatin, leucylglycylglycine, leucylglycine and chloroacetyltyrosine. The same substrates undergo hydrolysis when the enzyme solutions are subjected to prolonged dialysis in 'Cellophane' bags against running tap water. If, however, the dialysed solutions are filtered by suction through kieselguhr layers, only leucylglycylglycine of all the above substrates is split. The addition of dialysate, inactivated by heating, does not restore the activity of the filtrates towards the other four substrates.
