NADP nicotinamide-adenine-dinucleotide phosphate → NADPH

참여 물질

반응 단계

The enzymic activity is determined according to the following procedure: 10.8 g of trehalose, 860 mg of glutathione, and 17.2 mg of Na2EDTA are dissolved in a 57 mM potassium phosphate buffer solution (pH 7.0) to prepare 100 ml of a solution. A mixture of 1.40 ml of the thus prepared solution, 100 μl of a 20 mM NADP+ solution, 100 μl of a 26 mM magnesium chloride solution, 100 μl of a 1.34 mM glucose 1,6-diphosphate solution, 100 μl of a 31 unit/ml phosphoglucomutase solution, 100 μl of a 35 unit/ml glucose 6-phosphate dehydrogenase solution, and 100 μl of a sample solution is incubated at 30° C. and the quantity of produced NADPH is monitored consecutively by means of absorption spectrophotometry at 340 nm. One unit refers to the amount of enzyme which is capable of producing 1 μmol of NADPH for 1 min. under the conditions.
