Description | 6-Phosphogluconate dehydrogenase ( ) (6PGD) is an oxidative carboxylase that catalyses the decarboxylating reduction of 6-phosphogluconate into ribulose 5-phosphate in the presence of NADP. This reaction is a component of the hexose mono-phosphate shunt and pentose phosphate pathways (PPP) [ , ]. Prokaryotic and eukaryotic 6PGD are proteins of about 470 amino acids whose sequence are highly conserved []. The protein is a homodimer in which the monomers act independently []: each contains a large, mainly α-helical domain and a smaller β-α-β domain, containing a mixed parallel and anti-parallel six-stranded β-sheet []. NADP is bound in a cleft in the small domain, the substrate binding in an adjacent pocket []. This family represents the NADP binding domain of 6-phosphogluconate dehydrogenase which adopts a Rossman fold. The C-terminal domain is described in . This domain can also be found in 3-hydroxyisobutyrate dehydrogenases (HIBADH) and related proteins [ ]. |
