A protease is a digestive enzyme. It breaks down long chains of proteins into shorter amino acids. Proteases have evolved a number of time. We know this because different kinds of protease can do the same reaction in completely different ways. Proteases are found in animals, plants, bacteria, archaea and viruses.
Protease can be divided into 6 types :
- serine proteases
- threonine proteases
- cysteine proteases
- aspartate proteases
- metallo proteases
- glutamic acid proteases
