Melatonin is known to influence a variety of biological processes including circadian rhythms, neuroendocrine, and cardiovascular and immune functions as well as thermoregulation. Melatonin is the chief secretory product of the pineal gland, although it is also produced in other organs. In this study, in vitro effects of melatonin on 6-phosphogluconate dehydrogenase from human erythrocytes and in vivo effects of melatonin on 6-phosphogluconate dehydrogenase from rat (Sprague-Dawley) erythrocytes were studied. Human erythrocyte 6-phosphogluconate dehydrogenase was purified in 3 steps, namely haemolysate preparation, ammonium sulphate fractionation (35-65%) and 2´,5´-ADP Sepharose-4B affinity gel chromatography. 6-Phosphogluconate dehydrogenase was purified with a recovery rate …
