Pathway

Carbohydrate degradation; pentose phosphate pathway; D-ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage): step 1/3. HAMAP-Rule MF_00966

Subunit structure

Homodimer. Ref.8

Sequence similarities

Belongs to the glucose-6-phosphate dehydrogenase family.

Biophysicochemical properties

Kinetic parameters:

KM=114 µM for glucose 6-phosphate (with NADP) Ref.7 Ref.8
