SERINE PROTEINASE Meaning and
Definition
-
A serine proteinase, also commonly known as serine protease, is a type of enzyme that belongs to a larger class of proteolytic enzymes. This class of enzymes is involved in breaking down proteins by cleaving peptide bonds, thereby facilitating various physiological processes and pathways within living organisms. Serine proteinases are named after the presence of a serine residue in their active sites, which is crucial for their catalytic activity.
These enzymes are characterized by their ability to hydrolyze peptide bonds selectively through a nucleophilic attack on the carbonyl group of the substrate. The serine residue within the active site acts as a nucleophile and forms a covalent bond with the peptide substrate, resulting in the breakdown of the peptide bond and the generation of two separate products.
Serine proteinases play vital roles in a wide range of biological processes, including digestion, blood coagulation, immune response, apoptosis, and protein activation. Examples of serine proteinases include trypsin, chymotrypsin, and elastase, which are found in the digestive system and are responsible for the breakdown of dietary proteins.
These enzymes are highly specific in their substrate recognition and catalytic activities, which enables them to perform their functions with precision. Dysfunction or dysregulation of serine proteinases can lead to various diseases and disorders, such as pancreatitis, inflammatory bowel diseases, and cancer. Therefore, understanding the mechanisms and regulation of serine proteinases is crucial in developing therapeutic interventions and treatments for these conditions.

Etymology of SERINE PROTEINASE
The word "serine proteinase" can be broken down into two parts: "serine" and "proteinase".
- "Serine" refers to the amino acid serine, which is one of the 20 amino acids that are the building blocks of proteins. Serine is named after the Latin word "sericum", meaning silk, due to its discovery in silk protein.
- "Proteinase" is derived from the word "protein" and the suffix "-ase". "Protein" originates from the French word "protéine", coined by Jöns Jacob Berzelius in 1838, which is a derivative of the Greek word "proteios", meaning "of prime importance". "-ase" is a suffix used in biochemistry to denote an enzyme, indicating that proteinases are enzymes that act on proteins.
