Glycosidases are useful for structural and functional studies of glycoproteins and glycolipids. To explore the highly suitable glycosidase sources among marine animals, glycosidase activities in the livers of various fishes and some mollusks were measured. Relatively high activities of various glycosidases were found in all the livers examined. β-N-Acetylhexosaminidase activity was extremely high in the livers of common octopus, sea breams, croaker, and common squid. α-N-Acetylgalactosaminidase activity was fairly high in all the livers and most dominant in skipjack liver. β-Galactosidase and α-mannosidase activities were also sufficiently high in the livers of sea breams, common octopus, common squid, yellowtail, and common horse mackerel to use these livers as the enzyme source. The extractability of glycosidases increased by approximately 20% after moderate autolysis of the livers.
