COMPOSITION CONTAINING NEW TRANSGLUTAMINASE DERIVED FROM LIVER OF FISHES AND PRODUCTION OF GELATINIZED MATERIAL OF PROTEIN USING THE SAME

摘要

PURPOSE:To obtain the subject composition inexpensively producible in a large amount, readily receivable because of familiarity in the human food history, capable of producing a gelatinized material of protein, containing a new transglutaminase derived from fish liver. CONSTITUTION:The objective composition contains 0.5 or more unit based on 1mg protein of a new transglutaminase derived from fish liver, catalyzing acyl transfer reaction between gamma-carboxyamide group of glutamine residue in peptide chain and a primary amine. The composition is preferably obtained from a supernatant liquid prepared by homogenizing a liver of a fish (preferably walleye pollack or red sea bream) and centrifuging.
