Rapid purification of human erythrocyte 6-phosphogluconate dehydrogenase by means of affinity chromatography. 1979

A Morelli

A rapid two-step procedure is reported by which homogeneous 6-Phosphogluconate dehydrogenase can be isolated from human erythrocytes. This method is based upon direct affinity chromatography of the hemolysates on adenosine 2',5'-bisphosphate-agarose (yielding a 4,500-fold purification), followed by anion exchange chromatography on a micro-column of DEAE-Sephadex. The present method represents a considerable simplification over previously available procedures for the purification of this enzyme protein from human erythrocytes.

UI MeSH Term Description Entries
D010734 Phosphogluconate Dehydrogenase An enzyme of the oxidoreductase class that catalyzes the reaction 6-phospho-D-gluconate and NADP+ to yield D-ribulose 5-phosphate, carbon dioxide, and NADPH. The reaction is a step in the pentose phosphate pathway of glucose metabolism.
