| Summary: | </i><b>Abstract: <i></b><p align=\"justify\"> The phosphatases indicated in this research are phosphomonoesterases, i.e. enzymes that catalyze the hydrolysis of the -P-O- bond of orthophosphoric monoesters and producing ROH and H<sub>3</sub>PO<sub>4</sub>. These enzymes are widely distributed in living organisms but, until now, the enzyme have not been reported present in pineapple.<p align=\"justify\"> The pineapple phosphatase was extracted, partially purified and characterized, using p-nitrophenyl phosphate as substrate. The result showed that, the enzyme had a pH optimum of 6.0, temperature optimum of 40°C. The Michaelis - Menten constant (Km) and its maximum velocity (Vmax) were 1.87 mM and 2.2452 μmol/min respectively. This pineapple acid phosphatase was not affected by metal ion Mg<sup>++</sup>. |
