Protein attributes

Sequence length	791 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

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 + H2O = 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	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). Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.6 Ref.7
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.
Sequence caution	The sequence CAH18137.1 differs from that shown. Reason: Erroneous initiation.
