6-phosphogluconate dehydrogenase signature


6-phosphogluconate dehydrogenase (EC (6PGD) catalyzes the third step in the hexose monophosphate shunt, the decarboxylating reduction of 6-phosphogluconate in to ribulose 5-phosphate.

Prokaryotic and eukaryotic 6PGD are proteins of about 470 amino acids whose sequence are highly conserved [1]. As a signature pattern we have selected a region which has been shown [2], from studies of the sheep 6PGD tertiary structure, to be involved in the binding of 6-phosphogluconate.
