The stereochemistry of the nicotinamide adenine dinucleotide-specific isocitric dehydrogenase reaction.

Biochemical basis of obligate autotrophy in Nitrosomonas europaea.

The specific activities of isocitric dehydrogenase, alpha-ketoglutaric dehydrogenase, succinic dehydrogenase, malic dehydrogenase, and reduced nicotinamide adenine dinucleotide (NADH) oxidase were determined in extracts of Nitrosomonas europaea and compared with the corresponding values for Anacystis nidulans and autotrophically grown Hydrogenomonas eutropha. In common with other obligate autot...

REASSOCIATION AND REACTIVATION OF GLUCOSE 6-PHOSPHATE DEHYDROGENASE FROM STREPTOMYCES AUREOFACIENS AFTER DENATURATION BY 6 M UREA

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...

Diphosphopyridine nucleotide isocitric dehydrogenase from animal tissues.

Triphosphopyridine nucleotide linked isocitric dehydrogenase in bacteria.

The conversion of isocitric acid to alpha-ketoglutarate has been demonstrated both in animal tissues (Martius, 1937; Krebs and Johnson, 1937; Adler et al., 1939; Ochoa, 1948) and in yeast (Kornberg and Pricer, 1951; Foulkes, 1951). Triphosphopyridine nucleotide was first implicated as a specific coenzyme for this reaction by Adler et al. (1939). Recently Kornberg and Pricer (1951) found in yeas...

Changes in fungi with age. II. Respiration and respiratory enzymes of Rhizoctonia solani and Sclerotium bataticola.

Van Etten, James L. (University of Illinois, Urbana), H. Peter Molitoris, and David Gottlieb. Changes in fungi with age. II. Respiration and respiratory enzymes of Rhizoctonia solani and Sclerotium bataticola. J. Bacteriol. 91:169-175. 1966.-The rate of respiration of Rhizoctonia solani and Sclerotium bataticola decreased with age. This decrease in respiratory rate might be produced by a decrea...
