説明

Effects of chemical modification of carboxyl groups in the hemolytic lectin CEL-III on its activities were investigated. When carboxyl groups were modified with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and glycine methyl ester, hemolytic activity of CEL-III decreased as the EDC concentration increased, accompanied by reduction of oligomerization ability and hemagglutinating activity. However, binding ability of CEL-III for immobilized lactose was retained fairly well after modification, suggesting that one of two carbohydrate-binding sites might be responsible for such inactivation of CEL-III.<br>
