IPA Database by CCFA

  Protein-glutamine γ-glutamyltransferase
Substance Information
Synonyms of Substance Name  
CAS Number  80146-85-6
INS Number  
IUBMB Number
Technological Function [Category (for enzyme preparations only)]  Food enzymes (including immobilized enzymes)
Description  Transglutaminase catalyzes the formation of covalent bonds between lysine and glutamine residues in the food protein. This reaction leads to the build-up of a stable protein network with high binding strengths of the participating amino acid residues. This helps to bring about improvement in texture, mouth-feel and water retention of protein-rich foods
Functional Use  

protein glutamine + alkylamine = proteinN5-alkylglutamine + NH3

Production Organism(for food enzymes)  Streptomyces mobaraensis (formerly Stretoverticillium mobaraense)
Donor Organism(for food enzymes)
