Serine protease

Serine proteases are a group of enzymes that play a crucial role in various biological processes by breaking down proteins. They are called "serine" proteases because they use an amino acid called serine in their active site to cut peptide bonds between proteins. This process is essential for digestion, blood clotting, and immune responses, as well as other cellular functions. These enzymes are found in many organisms, including humans, and their precise activity and regulation are vital for maintaining health. Dysfunctions in serine proteases can lead to diseases, making them important targets for medical research.
