The stereochemistry of the a-ketoglutarate produced in the reaction of nicotinamide adenine dinucleotide-specific isocitric dehydrogenase with threO-D,-iSOCitrk acid-P-T has been determined. The product retained the tritium of the substrate in the p position without inversion. This is similar to the tinding with the nicotinamide adenine dinucleotide phosphate-specific enzyme. The products of th...

Cell-free particles from Pseudomonas rubescens have been shown to reduce hydroxocobalamin to vitamin B(12r). The particles are unable to reduce the B(12r) to B(12s). The reduction of hydroxocobalamin is dependent upon reduced nicotinamide adenine dinucleotide and is stimulated by flavin adenine dinucleotide. Cobinamide and diaquocobinamide were reduced at 25 and 10%, respectively, of the rate o...

Anaerobic incubations of rat liver microsomes convert daunorubicin into at least six or seven aglycones in the presence of reduced nicotinamide adenine dinucleotide phosphate or a reduced nicotinamide adenine dinucleotide phosphate-generating system. The partial identification of some of the aglycones is based on cochromatographs of chemically synthesized derivatives by isocratic high-pressure ...

Glucose 6-phosphate dehydrogenase (G6PD) from Streptomyces aureofaciens was purified and denatured in 6 M urea. Denaturation led to complete dissociation of the enzyme into its inactive monomers, 98% loss of the enzyme activity, about 30% decrease in the protein fluorescence and a 10 nm red shift in the emission maximum. Dilution of urea-denatured enzyme resulted in regaining of the enzyme acti...

Human erythrocyte glucose 6-phosphate dehydrogenase (o-glucose 6-phosphate :nicotinamide adenine dinucleotide phosphate oxidoreductase, EC 1.1.1.49) was purified by column chromatography with diethylaminoethyl cellulose, calcium phosphate gel, carboxymethyl cellulose, diethylaminoethyl Sephadex, and carboxymethyl Sephadex. A homogeneous preparation was obtained in over-all yield of about 50%. T...

This study shows a marked increase in the activity of the soluble enzyme DT-diaphorase and of the histochemical activity of the reduced nicotinamide adenine dinucleotide and reduced nicotinamide adenine dinucleotide phosphate nitroblue tetrazolium menadione-mediated reductases in human colonic carcinomas when compared with the enzymatic activities of portions of the colon uninvolved by the carc...
