Specific activity of an enzyme

WebEnzymatic activity assays are predominately performed by researchers to identify the presence or quantity of a specific enzyme in an organism, tissue, or sample. Examples of such enzymes include α-amylase, catalase, laccase, peroxidase, lysozyme, and reporter enzymes alkaline phosphatase, and luciferase. WebEnzyme activity may be turned "up" or "down" by activator and inhibitor molecules that bind specifically to the enzyme. Cofactors. Many enzymes are only active when bound to non-protein helper molecules known as cofactors. Compartmentalization.
