ENZYME INACTIVATION Meaning and
Definition
-
Enzyme inactivation refers to the process by which an enzyme loses its catalytic activity and is unable to perform its biological function. Enzymes are protein molecules that act as biological catalysts, facilitating and accelerating chemical reactions in living organisms. They play crucial roles in various physiological and metabolic processes. However, several factors can lead to the loss of enzyme activity, rendering them inactive or less effective.
Enzyme inactivation can occur through various mechanisms. One common method is through denaturation, where enzymes undergo structural changes that disrupt their active site, preventing the binding of substrate molecules. Denaturation can be triggered by extreme temperatures, pH changes, or exposure to harsh chemicals, which disrupt the hydrogen and ionic bonds that maintain enzyme structure.
Another mechanism of enzyme inactivation is through the action of inhibitors, molecules that bind to specific sites on an enzyme and interfere with its catalytic function. Inhibitors can be reversible or irreversible, depending on their ability to dissociate from the enzyme. Reversible inhibitors may compete with substrates for the active site or bind to a different site, altering the enzyme's conformation. Irreversible inhibitors form strong covalent bonds with the enzyme, permanently disrupting its structure and function.
Enzyme inactivation can also occur due to proteolysis, where enzymes are degraded by proteases. Proteases are enzymes that break down proteins, including other enzymes, by cleaving peptide bonds. Additionally, genetic mutations or modifications in an enzyme's amino acid sequence can lead to structural alterations that render it inactive.
Understanding the mechanisms of enzyme inactivation is crucial in various fields such as medicine, biochemistry, and biotechnology. It allows researchers to develop strategies to stabilize or reactivate enzymes for therapeutic purposes or to enhance industrial processes involving biocatalysis.

Etymology of ENZYME INACTIVATION
The word "enzyme" is derived from the Greek word "énzymos", which means "in leaven" or "yeast". The term was coined by the German physiologist Wilhelm Kühne in 1878. "Inactivation" is derived from the Latin word "inactivatus", which means "made ineffective or inactive". Therefore, "enzyme inactivation" refers to the process of rendering an enzyme ineffective or inactive.
