Proteases are enzymes that play a crucial role in the breakdown of proteins into amino acids. They are involved in various biological processes, such as digestion, cell signaling, and protein degradation. Proteases are classified into several families based on their structure, catalytic mechanism, and substrate specificity. Research in the field of proteases focuses on understanding the biochemical and physiological functions of these enzymes, their roles in health and disease, and their potential as therapeutic targets for various conditions, including cancer, cardiovascular diseases, and inflammatory disorders. Additionally, protease research also explores the development of protease inhibitors as pharmaceutical agents to modulate protease activity and treat related diseases.
