Glucose 6-phosphate dehydrogenase (G6PD) was purified from turkey erythrocytes by ammonium sulphate precipitation and followed by ADP Sepharose affinity gel chromatography. The yield was 49.71% and specific activity of the enzyme was found to be 44.16 EU/mg protein. By gel filtration the molecular mass was found to be 75 kDa. The enzyme had an optimum pH at 9.0, and optimum temperature at 50°C. K m and V max for NADP + and glucose 6- phosphate (G6-P) as substrates were also determined and effects of inhibitors such as ATP, NADH and NADPH were examined.
