Native Phaseolus vulgaris Alpha-Amylase Inhibitor

Cat No.
A proteinaceous inhibitor of the digestive enzyme alpha-amylase (1,4-a-D-Glucan glucanohydrolase; EC has been isolated and purified from kidney beans Phaseolus vulgaris. It is a glycoprotein and it specifically inhibits corresponding plant, bacterial and fungal enzymes. Maximum inhibitory activity, against alpha-amylase, occurs at 37° C and pH 5.5. The inhibitor has a molecular weight of 45,000-50,000. Similar alpha-amylase inhibitors also occur in wheat, rye and some other beans.
