چکیده
Nicotinamide-(S-methylmercury-thioinosine) dinucleotide was formed by reaction of nicotinamide-(6-thiopurine) dinucleotide with methylmercury chloride. The compound exhibits coenzyme properties in the test with LDH (Km=1.5 X 10(-4) M, Vmax=12500) and LADH (Km=1.7 X 10(-4) M, Vmax=27) and inactivates YADH and GAPDH. From incubations with LDH and LADH the mercury containing coenzyme could be regarded by column be qualified for the X-ray structure analysis of the coenzyme-enzyme complex for some dehyrogenases based on the proportion of the heavy metal.

Glyoxylate dehydrogenase (glyoxylate:NAD+ oxidoreductase) was purified 600-fold in three steps from crude extracts of the fungus Sclerotium rolfsii (Corticium rolfsii Curzi). Two of the purification steps involved dye-affinity chromatography. The enzyme is a tetramer of Mr 250 000, with identical subunits of Mr 57 000. Inhibition studies suggest that there is one essential thiol group per activ...

Lactate dehydrogenase isolated from vertebrate tissues catalyzes the reversible oxidation of L-lactic acid to pyruvic acid. The catalysis requires nicotinamide adenine dinucleotide (NAD’) as a coenzyme and is specific for the A-hydrogen of the nicotinamide ring (1) (Fig. 1). Although the enzyme is tetrameric, no cooperative effects have been observed between subunits (2). Each identical subunit...

The generalization that 'when a metabolic sequence involves consecutive nicotinamide-adenine dinucleotide-dependent reactions, the dehydrogenases have the same stereospecificity' was tested and confirmed for three metabolic sequences. (1) NAD+-xylitol (D-xylulose) dehydrogenase and NADP+-xylitol (L-xylulose) dehydrogenase are both B-specific. (2) D-Mannitol 1-phosphate dehydrogenase and D-sorbi...

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...
