Glossary

# Enzyme inhibitor

An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. Inhibitors may be reversible, competing with substrate or binding elsewhere, or irreversible, forming covalent bonds. Peptide and small-molecule inhibitors are used in research to study enzyme function and pathways.
