Absorbance values can be transformed to units of concentration via the Beer-Lambert law. We must accept the approximation of the Molar Extinction Coefficient for PNPA hydrolysis at 428.7nm as 12000 M^-1 cm^-1. An example calculation is supplied in the table. Graphing time versus concentration and determining the slope of the line yields the enzyme's velocity in M/min. 1mg/mL of PNPA is saturating conditions which implies the Vmax is also the slope. The reaction volume total times Vmax yields Units of Enzyme Activity. This value can be used as a relative comparison tool for enzyme performance in given conditions.
