NOVEL ENZYME AND PRODUCTION OF PROTEIN GELATINIZED PRODUCT USING SAID ENZYME

摘要

PURPOSE:To produce a protein gelatinized product, by reacting a transglutaminase capable of catalyzing an acylation arrangement reaction of gamma-carboxylamide group of a glutamine residue in peptide chain in the absence of Ca<2+> with a protein. CONSTITUTION:A protein-containing solution or slurry having >=1.0wt.% protein concentration is prepared. A transglutaminase capable of catalyzing an acyl arrangement reaction of gamma-carboxylamide group of glutamine residue in a peptide chain in the absence of Ca<2+> is added to the protein-containing solution or slurry and reacted with the protein to provide the protein gelatinized product. The above-mentioned transglutaminase is preferably added to the protein- containing solution or slurry at an amount of 0.01-2,000 unit based on 1.0g protein. Furthermore, the microorganism having transglutaminase producing- ability incudes bacterium belonging to the genus Streptoverticillium.
