Abstract

The action of B. subtilis saccharifying amylase on starch has been examined. It has been found that high yields of reducing sugar and glucose are produced from both starch solutions and starch gels upon prolonged reaction. The enzyme has also been found to have maltase and cyclodextrinase activities and to produce an almost quantitative yield of glucose from β‐cyclodextrin. Attempts to separate or differentiate the amylase, maltase and cyclodextrinase activities by electrophoresis, inhibitors, heat inactivation and hydroxylapatite chromatography have been unsuccessful, and it is concluded that the enzyme activities are all due to one molecular species.

Modification of porcine pancreatic a-amylase (PPA) and Taka-amylase A(TAA) with diethyl pyrocarbonate (DEP) causes activation of the release of p-nitrophenol from g-nitrophenyl a-maltoside (G2PNP), and a decrease in amylase activity (hydrolysis of o-1,4 glucosidic bonds in starch) [l-4]. Among the p
