SERINE PROTEINASES Meaning and
Definition
-
Serine proteinases, also known as serine proteases, are a group of enzymes that play a crucial role in various biological processes, particularly in protein metabolism and digestion. These enzymes belong to the broader category of proteases, which are responsible for breaking down proteins into smaller peptides or amino acids.
Characteristically, serine proteinases demonstrate a high degree of specificity in terms of their substrate recognition. They contain a highly conserved amino acid residue, serine, at their active site. This serine residue performs a nucleophilic attack on the peptide bond of the target protein substrate, resulting in its hydrolysis or cleavage.
Serine proteinases are involved in numerous physiological processes in organisms. In humans, these enzymes are critical for blood coagulation, tissue remodeling, immune response, and digestion. Some well-known examples of serine proteinases include trypsin, chymotrypsin, and elastase. Trypsin is mainly produced in the pancreas and assists in the breakdown and absorption of dietary proteins. Chymotrypsin, on the other hand, is responsible for further breaking down peptides produced by trypsin. Elastase is primarily involved in the maintenance and repair of connective tissues.
In addition to their natural roles, serine proteinases have also found applications in various industries, including the production of pharmaceuticals, detergents, and food processing. Understanding the mechanisms and functions of these enzymes is therefore of great importance in both biological research and commercial applications.

Etymology of SERINE PROTEINASES
The word "serine proteinases" is derived from the combination of two components - "serine" and "proteinases".
1. Serine: Serine is an amino acid that plays a crucial role in the structure and function of proteins. It is derived from the Latin word "sericum" meaning silk, as it was first isolated from silk protein. The term "serine" was coined by the German chemist Emil Fischer in 1902.
2. Proteinases: Proteinases, also known as proteases, are enzymes that break down proteins into smaller peptides or amino acids. The term "proteinase" is a combination of "protein" and the suffix "-ase", which is used to denote an enzyme.
When combined, "serine proteinases" refers to a group of proteases that contain a serine residue in their active sites.
