The amount of product, p-nitrophenol, is determined by reading the absorbance at 405 nm and using a molar extinction coefficient of 18,000 M-1 cm-1 (16,000 M-1cm-1 for 0.5 M EDTA) (1, 3). One unit of the protein phosphatase activity is defined as the amount of enzyme that hydrolyzes 1 nanomole of PNPP in one minute at 30°C in a total reaction volume of 50 μl under standard reaction condition.
