Enzymatic purity
WebPurity of the enzyme preparations The enzyme preparations need not be of the highest purity, since neither sedoheptulose diphosphate nor other phosphate esters form glucose-6-phosphate. However, the preparations must be free from non-specific phosphatases, because hydrolysis of fructose-1,6-diphosphate at the C-6-phosphate group would result … The % purity is 100% × (specific activity of enzyme sample / specific activity of pure enzyme). The impure sample has lower specific activity because some of the mass is not actually enzyme. If the specific activity of 100% pure enzyme is known, then an impure sample will have a lower specific activity, allowing purity … See more Enzyme assays are laboratory methods for measuring enzymatic activity.
