Description

Cucumisin CAS NO 82062-89-3 is a serine protease enzyme isolated from the sarcocarp of melon fruits (*Cucumis melo*). This enzyme is valued for its unique proteolytic activity and stability under various conditions, making it a versatile biocatalyst. It is primarily utilized in the food processing, biotechnology, and research sectors for protein hydrolysis, peptide synthesis, and as a model enzyme in biochemical studies.

Application

• Food Protein Modification: Used for the hydrolysis of plant and dairy proteins to improve functional properties like solubility, emulsification, and flavor profile.
• Biocatalysis & Peptide Synthesis: Employed in enzymatic synthesis of specific peptides and as a catalyst in organic media for chiral resolutions.
• Biomedical & Diagnostic Research: Serves as a model protease in enzymatic assays, substrate specificity studies, and protease inhibitor screening.
• Detergent Formulations: Acts as an active ingredient in specialty enzymatic cleaners for breaking down protein-based stains.
• Brewing & Fermentation: Aids in the clarification process by degrading haze-forming proteins in beverages.
• Leather Processing: Used in the bating step to remove unwanted proteins and soften hides.
