GLUCOSE-6-PHOSPHATE DEHYDROGENASE TYPE VII FROM BAKERS YEAST

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 has been used in a study to investigate the effect of dehydroepiandrosterone on cell growth and mitochondrial function in TM-3 cells. Glucose-6-phosphate dehydrogenase has also been used in a study to investigate the incidence of apoptosis and transcript abundance in bovine follicular cells. 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.

Unit Definition

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.

Physical form

Crystalline suspension in 3.2 M (NH₄)₂SO₄ solution, pH 7.0
