Özet
Glucose-6-phosphate dehydrogenase (D-glucose-6-phosphate: NADP(+) oxidoreductase, EC 1.1.1.49; G6PD) was purified from coriander (Coriandrum sativum) leaves; the kinetic behavior and some properties of the enzyme were also investigated. The purification was done at 4C and involved two steps: ammonium sulfate fractionation, and DEAF-Sephadex A50 ion exchange chromatography. The enzyme was obtained with a yield of 26.4% and had a specific activity of 1.826 U/mg protein. Optimum pH, stable pH, optimum temperature, molecular weight, K-M and V-max values for NADP(+) and glucose 6-phosphate (G6-P) were also determined.
