Notes:
The pineapple stem is an excellent source of two acid phosphatases. Although the enzymes are stable between pH 4.0 and 8.5 and are not readily surface-denatured, yet the assay values are not too reproducible. Micelle formation may account for the erratic results. The enzyme shows optimum activity at pH 6.0 and requires no metal cofactor. Certain metals, such as magnesium, stabilize the enzyme. Molybdate and hydrogen peroxide are the most potent inhibitors. Dibasic phosphate is about three times as potent an inhibitor as dibasic arsenate.
