Nicotinamide 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...

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 lysin...

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 کاملRegulation of the nicotinamide adenine dinucleotide-specific isocitrate dehydrogenase from a higher plant. The effect of reduced nicotinamide adenine dinucleotide and mixtures of citrate and isocitrate.
The NAD+-specific isocitrate dehydrogenase from pea stems is shown to respond to the mole fraction of NADH when total NAD (NAD+ plus NADH) is kept constant. Fifty per cent inhibition occurs when the mole fraction of NADH is 0.1. In this region the enzyme is extremely sensitive to NADH concentration and it is suggested that this acts in a similar manner to energy charge in other systems. In an a...
