What is it: A Process Control Plan (PCP) is a summary of defect prevention and reactive detection techniques. The overall intent of the PCP is to control the product characteristics and the associated process variables to ensure capability (around the identified target or nominal) and stability of the product over time.
Various compounds can reduce the activity of enzymes. They may act in a variety of different ways, and indeed may be reversible or irreversible inhibitors of the enzyme. An irreversible inhibitor causes covalent modification of the enzyme, so that its activity is permanently reduced.
An uncompetitive inhibitor cannot bind to the free enzyme, only to the enzyme-substrate complex; hence, these types of inhibitors are most effective at high substrate concentration. In the presence of the inhibitor, the enzyme-substrate complex is inactive.This type of inhibition is rare.n uncompetitive inhibitor cannot bind to the free enzyme, only to the enzyme-substrate complex; hence, these types of inhibitors are most effective at high substrate concentration.
