• 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

• uncompetitive inhibition — inhibition of an enzyme by a substance that binds reversibly to the enzyme substrate complex. The enzyme substrate inhibitor complex cannot yield the normal product until the inhibitor is released …   Medical dictionary

• noncompetitive inhibition — inhibition of enzyme activity by a substance that combines with the enzyme at a site other than that utilized by the substrate, causing a change in enzyme configuration and a decrease in activity. Similarly, the inhibition of a hormone or… …   Medical dictionary

• allosteric inhibition — inhibition of an enzyme by binding of an inhibitor at an allosteric site that causes at the catalytic site either reduced binding affinity of the enzyme for the substrate or decreased rate of catalytic turnover …   Medical dictionary
