Protease and peptidase are two types of proteolytic enzymes. Both can be produced via recombinant DNA technology and both are capable of degrading proteins by cleaving peptide bonds of proteins. 

Both, protease and peptidase, are most abundant in animals and play key roles in protein digestion in the digestive system. They are also present in plants, bacteria, viruses, and fungi. 

Both are used extensively in the food, leather, and wool industries.
