Example of non-competitive inhibition

WebCompetitive inhibitors impair reaction progress by binding to an enzyme, often at the active site, and preventing the real substrate from binding. At any given time, only the competitive inhibitor or the substrate can be bound to the enzyme (not both). That is, the inhibitor and substrate compete for the enzyme. Competitive inhibition acts by ... WebMethods and systems are described for identification and characterization of allosteric sites in proteins and enzyme molecules. The disclosed methods allow for identification of natural and true binding sites on surface regions of protein and enzyme molecules by following the pathways of energy flow between the activity center to the surface regions.
