PURPOSE: To produce a protein gelatinized product, by reacting a transglutaminase capable of catalyzing an acylation arrangement reaction of γ-carboxylamide group of a glutamine residue in peptide chain in the absence of Ca2+ 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 γ-carboxylamide group of glutamine residue in a peptide chain in the absence of Ca2+ 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 0.01W2,000 unit based on 1.0g protein. Furthermore, the microorganism having transglutaminase producing- ability incudes bacterium belonging to the genus Streptoverticillium.
