Allosamidin was a potent competitive inhibitor of enzyme activity (Ki = 0.23 microM). WebAllosteric regulation is the regulation of an enzyme or other protein by binding an effector molecule at the protein's allosteric site (that is, a site other than the protein's active site). Effectors that enhance the protein's activity are referred to as allosteric activators, whereas those that decrease the protein's activity are called ...
WebIC 50 represents the concentration at which a substance exerts half of its maximal inhibitory effect. This value is typically used to characterize an antagonist of a biological process (ex. phosphorylation). In pharmacology, it is an important measure of potency for a given agent. Traditionally, this value is expressed as a molar concentration.
