  Protein-glutamine glutaminase
Substance Information
Synonyms of Substance Name  
CAS Number  62213-11-0
INS Number  
IUBMB Number
Technological Function [Category (for enzyme preparations only)]  Food enzymes (including immobilized enzymes)
Description  Protein glutaminase catalyzes the deamidation of glutaminyl residues in the substrate polypeptide, resulting in the conversion of glutaminyl residues to glutamyl residues and release of ammonia. This improves the protein functionality in food. It allows the modified protein to be used in small amounts for emulsification, foaming, or other functional uses.
Functional Use  

protein L-glutamine + H2O = protein L-glutamate + NH3

Production Organism(for food enzymes)  Chryseobacterium proteolyticum
Donor Organism(for food enzymes)  
Area of Usage
Area Of Utilization  Softening dough for baking, increasing protein solubility, improving texture of processed food products and reducing food protein allergenicity
