ABSTRACT
Glucose 6-phosphate dehydrogenase (D-glucose 6-phosphate NADP+ oxidoreductase, EC 1.1.1.49; G6PD) was purified from Lake Van fish (Chalcalburnus tarichii pallas, 1811) liver, using a simple and rapid method, and some characteristics of the enzyme were investigated. The purification procedure was composed of two steps:
homogenate preparation and 2¡ä, 5¡ä-ADP Sepharose 4B affinity gel chromatography, which took 7¨C8 hours. Thanks to the two consecutive procedures, the enzyme, having specific activity of 38 EU/mg protein, was purified with a yield of 44.39% and 1,310 fold. In order to control the enzyme purification SDS polyacrylamide gel electrophoresis (SDS-PAGE) was done. SDS polyacrylamide gel electrophoresis showed a single band for enzyme. Optimal pH, stable pH, optimal temperature, Km and, Vmax values for NADP+ and glucose 6- phosphate (G6P) were also determined for the enzyme. In addition, molecular weight and subunit molecular weights were found by sodium dodecyl sulfate polyacrilamide gel electrophoresis (SDS-PAGE) and gel filtration chromatography respectively (AU)RESUMEN
