Discover what enzyme inhibition is and how it works. Learn about the types of enzyme inhibitions, understand reversible and irreversible inhibitions, and see some examples. Updated: 11/21/2023 What Is Enzyme Inhibition Enzymes are biological catalysts; they speed up chemical reactions but they ar...
Enzyme Inhibition Enzyme inhibitors are usually proteins and are used by the body to stop the enzyme activity. There are three main types of enzyme inhibitions:Competitive,non-competitiveanduncompetitive inhibition. Competitive Inhibition A specific part on a substrate where enzyme acts is called as an...

Examples: Various heavy metal ions (Ag+, Hg2+, Pb2+) inhibit the activity of a variety of enzymes like urease. c. Uncompetitive inhibition Uncompetitive inhibition is the inhibition of enzymatic activity by the binding of the inhibitor at an allosteric site like in the case of noncompetitive ...

thereby deforming its active site and preventing it from reacting with its substrate. This latter type of noncompetitive inhibition is calledallosteric inhibition; the place where the inhibitor binds to the enzyme is called the allosteric site. Frequently, an end-product of a metabolic pathway serves...
With classical competitive inhibitors, an increase in substrate concentration due to decreased metabolism can overcome inhibition. Examples of slow-binding inhibitors and their target enzymes include methotrexate and dihydrofolate reductase, enalopril and angiotensin-converting enzyme, allopurinol and xanthine: ...
There are certain factors that help regulate enzymes that include genetic enzyme regulation, compartmentalization, substrate concentration, degradation of enzymes, alteration of environmental factors, modification of zymogens, covalent modification, allosteric regulation, and inhibition. Genetic Regulation Genetic...
