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.
b-galactosidase (lactase) Suicide Inhibition This type of enzyme inhibition results in the stoichiometric covalent modification of a side chain on an amino acid in the active site of an enzyme. The inhibitor chemically resembles a (one of the) substrate(s) and binds in the active site in the same way as the substrate(s) binds.
