Studies on the Digestive Enzymes of Veneridae Soxidonus purpurtus Sowerby I Some Enzymatic properties of Amylase

The enzymatic activity of amylase which was isolated from a shell fish Veneridae Soxidmnus purpuratus Sowerby(Korean name"Gai-jo-gai") was studied and the obtained results were as follows: (1) The optimum pH of the enzyme was Ca. 6.2~6.4. (2) Prohibiting activity of metallic ions for the enzymatic activity was the order of 1/1000M-Mg++>1/1000M-Sr++> 1/000M-Na+, and Ca++ ion''s prohibiting action was hardly showed. (3) Of 3specimens of amylase from Heptapancreas, Gastro-intestine and crystalline style, the highest activity was shown by amylase from crystalline style, and the other two showed almost same degree of activity. (4) Heptapancreas Amylase from the shell fish showed remarkably higher enzymatic activity than the pancreas amylase from a pig.
