proteinase
Học thuậtThân thiện
Definition
Noun: An enzyme that catalyzes the breakdown of proteins into smaller peptide fragments and individual amino acids through the biochemical process called proteolysis.
Usage
Proteinase is a scientific term used primarily in biochemistry, molecular biology, and related fields. It refers to a specific class of enzymes responsible for protein digestion or degradation.
Examples
- Scientific Context:
- The experiment required a specific proteinase to digest the sample.
- Pepsin is a gastric proteinase that breaks down food proteins in the stomach.
- General Context:
- Researchers are studying the function of a novel proteinase.
- The activity of the proteinase was measured over time.
Advanced Usage
- "Proteinase inhibitor": A substance or molecule that blocks the activity of a proteinase.
- The drug acts as a proteinase inhibitor, preventing viral replication.
- "Serine proteinase": A major class of proteinases characterized by a serine residue in their active site.
- Trypsin is a well-known example of a serine proteinase.
Variants and Related Words
