WebEnzyme Activity Assays. Enzymatic 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 = moles of substrate converted per unit time = rate × reaction volume. Enzyme activity is a measure of the quantity of active enzyme present and is thus dependent on conditions, which should be specified. The SI unit is the katal, 1 katal = 1 mol s−1, but this is an excessively large unit.
