Purified recombinant E.coli G6 PD protein Expression System: E.coli Bioactivity: Specific activity is 8-10 units/mL obtained by measuring the increase of NADPH in absorbance at 340 nm resulting from the reduction of NAD or NADP. One unit oxidizes 1.0 m D-glucose-6-phosphate to 6-phospho-D-gluconate per min in the presence of beta-NADP at pH 7.4 at 25 °C. Molecular weight on SDS-PAGE will appear higher.
G6PD protein has been used in SDS PAGE and may be suitable for use in other assays to be determined by the end user.
实验流程
Prepare a 3 mL reaction cocktail into a suitable container: The final concentrations are 53 mM gylcylglycine, 3 mM D-glucose 6-phosphate, 0.63 mM beta-NADP, 13 mM MgCl2. 2. Equilibrate to 25 °C and monitor at A340 nm until the value is constant using a spectrophotometer. 3. Add 4 µg of recombinant G6PD into reaction cocktail and mix immediately. 4. Record the increase at A340 nm for 5 minutes.

Glucose-6-phosphate dehydrogenase (G6PD) is the rate-limiting enzyme of the pentose phosphate pathway, a metabolic pathway that supplies reducing energy to cells by maintaining the level of NADPH. G6PD converts glucose-6-phosphate into 6-phosphogluconolactone and simultaneously produces NADPH. The NADPH in turn maintains the level of glutathione in these cells that helps protect the red blood cells against oxidative damage. G6PD deficiency cause acute hemolytic anemia. Recombinant G6PD protein was expressed in E. coli and purified by conventional chromatography techniques.
