Physical and Kinetic Properties of the Nicotinamide Adenine Dinucleotide-specific Glutamate Dehydrogenase Purified from Chlorella sorokiniana.
The nicotinamide adenine dinucleotide-specific glutamate dehydrogenase (l-glutamate:NAD(+) oxidoreductase, EC 1.4.1.2) of Chlorella sorokiniana was purified 1,000-fold to electrophoretic homogeneity. The native enzyme was shown to have a molecular weight of 180,000 and to be composed of four identical subunits with a molecular weight of 45,000. The N-terminal amino acid was determined to be lys...
متن کاملPurification and properties of the inducible nicotinamide adenine dinucleotide phosphate-specific glutamate dehydrogenase from Chlorella sorokiniana.
The nicotinamide adenine dinucleotide phosphate-specific glutamate dehydrogenase (NADP-GDH) of Chlorella sorokiniana was purified 260-fold to electrophoretic homogeneity in six steps. Depending on the techniques used, the native enzyme appeared to have a molecular weight of 290,000 or 410,000 and to be composed of five to seven identical subunits with a molecular weight of 58,000. The amino aci...

متن کاملNicotinamide adenine dinucleotide phosphate-specific glutamate dehydrogenase of Neurospora.
Neurospora NADP-specific glutamate dehydrogenase that was treated with iodoacetate, iodoacetamide, or N-ethylmaleimide to block the thiol groups was cleaved with cyanogen bromide. Of the expected 10 peptides, based on a methionine content of 9 residues, 8 were obtained in pure form and 2 were handled as a mixture. The fragments ranged in size from 9 to 109 residues. In addition, there were isol...
متن کاملRegulation of Nicotinamide Adenine Dinucleotide Phosphate-specific Glutamate Dehydrogenase in Germinated Spores of Geotrichum candidum.
Germinating spores of Geotrichum candidum produce only a nicotinamide adenine dinucleotide phosphate-linked glutamate dehydrogenase. Synthesis of glutamate dehydrogenase was repressed by the presence of ammonia, whereas urea, glutamate, or glutamine were ineffective. The enzyme was not subject to catabolite repression and was localized in the cell sap fraction. The glutamate dehydrogenase has b...
