TRANSGLUTAMINASE ORIGINATING IN JAPANESE OYSTER

摘要

A transglutaminase originating in Japanese oyster, a gene coding for the transglutaminase, a plasmid having the gene, a microorganism transformed by the plasmid, a process for producing the target transglutaminase by culturing the microorganism, and a process for gelling a protein by using the transglutaminase originating in Japanese oyster. As compared with other transglutaminases, the invention traglutaminase has a novel property of being activated by calcium ions and further activated by adding thereto either sodium chloride or potassium chloride and is particularly useful as f gelling agent for foods.
