The use of various immobilized-triazine affinity dyes for the purification of 6-phosphogluconate dehydrogenase from Bacillus stearothermophilus. 1980

F Qadri, and P D Dean

1. 6-Phosphogluconate dehydrogenase from Bacillus stearothermophilus was purified approximately 260-fold on triazine-immobilized dye columns to a final specific activity of 54 mumol of NADP+ reduced/min per mg of protein and an overall yield of 62%. 2. An investigation of the capacities of different triazine dyes that inhibit 6-phosphogluconate dehydrogenase was carried out. Cibacron Blue F3G-A and Procion Red HE-3B strongly inhibited the enzyme in free solution and were therefore chosen as the ligands in the purification scheme. 3. KCl was found to be the most suitable agent for eluting 6-phosphogluconate dehydrogenase from Procion Red HE-3B-Sepharose 6B. NADP+ could specifically elute 6-phosphogluconate dehydrogenase from Cibacron Blue F3G-A-Sepharose 6B. 4. A study of the effect of temperature on the binding of pure 6-phosphogluconate dehydrogenase to both Cibacron Blue-Sepharose and Procion Red-Sepharose showed that the binding increased with an increase in temperature.

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.

D000345	Affinity Labels	Analogs of those substrates or compounds which bind naturally at the active sites of proteins, enzymes, antibodies, steroids, or physiological receptors. These analogs form a stable covalent bond at the binding site, thereby acting as inhibitors of the proteins or steroids.
