Effect of boronic acids on antifreeze proteins

Abstract
The activity of antifreeze glycoprotein from the blood serum ofBoreagadus saida was strongly inhibited by ions of organic boronic acids as well as by borate. The activity of nonglycoprotein from the blood serum ofPseudopleuronectus americanus, however, was not similarly inhibited. The inhibition by borate is thus specific for molecules with the carbohydrate moiety.
