  • Competitive inhibition — is a form of enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa. Contents 1 Mechanism 2 Equation 3 Derivation 4 …   Wikipedia

  • competitive inhibition — Inhibitor that occupies the active site of an enzyme or the binding site of a receptor and prevents the normal substrate or ligand from binding. At sufficiently high concentration of the normal ligand inhibition is lost: the Km is altered by the… …   Dictionary of molecular biology

  • competitive inhibition — inhibition of enzyme activity in which the inhibitor (substrate analogue) reversibly combines with catalytic sites, thus competing with the substrate for binding on the enzyme. The inhibition is reversible since it can be overcome by increasing… …   Medical dictionary

  • Enzyme inhibitor — Enzyme inhibitors are molecules that bind to enzymes and decrease their activity. Since blocking an enzyme s activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. They are also used as herbicides and… …   Wikipedia

  • Non-competitive inhibition — is a type of enzyme inhibition where the inhibitor reduces the activity of the enzyme, by binding not to the active site on the enzyme, but to a different site.[1] More specifically, it is a special instance of mixed inhibition where the… …   Wikipedia
