| IUBMB Number | 3.5.1.44 |
| 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 |
