General description
Glucose 6-phosphate dehydrogenase (G-6-P-DH) is a key regulatory enzyme in the first step of the pentose phosphate pathway. G-6-P-DH is a glycoprotein with a molecular mass of 128 kDa (gel filtration).
Application
Glucose-6-phosphate dehydrogenase is used to test ketose reductase activity in developing maize endosperm.
Biochem/physiol Actions
Glucose-6-phosphate dehydrogenase catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway<<<17>>>.
Glucose-6-phosphate dehydrogenase catalyzes the conversion of glucose-6-phosphate to 6-phosphogluconolacetone as the first step in the pentose phosphate pathway.
Physical form
Lyophilized and essentially sulfate-free; contains approx. 20% sodium citrate based on dry weight
Preparation Note
Prepared from G7877
Other Notes
One unit will oxidize 1.0 μmole of D-glucose 6-phosphate to 6-phospho-D-gluconate per min in the presence of NADP at pH 7.4 at 25 °C.
