Amylase inhibitors ofActiniae of the Caribbean Sea amylase inhibitor of protein nature fromStoichactis helianthus

Natural amylase inhibitors have been found in actiniae of the Caribbean Sea. From the actiniaS. helianthus an inhibitor has been isolated by gel filtration on Sephadex G-50 and ion-exchange chromatography on CM-cellulose that is highly specific in relation to the amylases of marine mollusks and is inactive in relation of the amylases from other sources.
