Total proteolytic activity in the hepatopancreas wa highest during postmolt. Trypsin and chymotrpsin activities were highest during intermolt. Specific inhibitors and zymograms of A. longinaris hepatopancreas extracts showed four trypsins (14.79, 15.49, 16.60, 17.38 kDa, respectively) and three chymotrypsins (21.38, 22.91, 27.54 kDa, respectively). Our results suggest that proteolytic activity in the hepatopancreas of A. longinaris is influenced by the moltin cycle. Types and activity of prawn digestive enzymes consititute background information to further study the digestive abilities of these organisms and will lead to understanding their nutritional needs and feeding ecology. 收起
