General annotation (Comments)

Function

Oxidizes glucose-6-phosphate and glucose, as well as other hexose-6-phosphates.

Catalytic activity

Beta-D-glucose + NAD(P)(+) = D-glucono-1,5-lactone + NAD(P)H.

D-glucose 6-phosphate + NAD(P)(+) = D-glucono-1,5-lactone 6-phosphate + NAD(P)H.

6-phospho-D-glucono-1,5-lactone + H(2)O = 6-phospho-D-gluconate.

Subcellular location

Endoplasmic reticulum lumen. Note= Microsomes, endoplasmic reticulum lumen.

Tissue specificity

Present in most tissues examined, strongest in liver.

Involvement in disease

Defects in H6PD are a cause of cortisone reductase deficiency (CRD) [MIM:604931]. In CRD, activation of cortisone to cortisol does not occur, resulting in adrenocorticotropin-mediated androgen excess and a phenotype resembling polycystic ovary syndrome (PCOS).

Sequence similarities

In the N-terminal section; belongs to the glucose-6-phosphate dehydrogenase family.

In the C-terminal section; belongs to the glucosamine/galactosamine-6-phosphate isomerase family. 6-phosphogluconolactonase subfamily.
