Reaktionsschritte

The phosphomonoesterase activity was measured under the following condition using 5′-inosinic acid as a substrate. The reaction was performed at 30° C. for 10 minutes in a reaction solution (1 ml) containing 10 μmol/ml of 5′-inosinic acid, 100 μmol/ml of MES/NaOH buffer (pH 6.0), and an enzyme. The reaction was stopped by adding 200 μl of 2 N hydrochloric acid. After that, precipitates were removed by centrifugation. Then, inosine produced by the hydrolytic reaction was quantitatively measured. An amount of enzyme to produce 1 μmol of inosine per 1 minute under this standard reaction condition was defined as 1 unit.
