Subtilisin Protease Feed Grade
CAS Number: 9014-01-1
Subtilisin Protease is a bacterial serine endoprotease used in animal feed to improve protein digestibility, reduce anti-nutritional proteins such as trypsin inhibitors, and enable higher inclusion of alternative plant proteins in monogastric diets. It hydrolyses peptide bonds releasing additional digestible amino acids beyond what the animal's own protease enzymes can achieve. Our thermostable formulation retains activity through standard pelleting.
