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...
متن کاملNicotinamide adenine dinucleotide glycohydrolase activity in guinea pig polymorphonuclear leukocytes.
An enzyme is present in extracts of guinea pig polymorphonuclear leukocytes which can catalyze the hydrolysis of pyridine nucleotides. The enzyme is equally active toward nicotinamide adenine dinucleotide (NAD) or NAD phosphate, has an acid pH optimum, and is inhibited by either nicotinamide or isonicotinic acid hydrazide. This enzyme might be involved in the regulation of the pyridine nucleoti...
متن کاملNicotinamide-adenine Dinucleotide-glycohydrolase Activity in Experimental Tuberculosis.
1. The specific NAD-glycohydrolase activity is increased 70 and 50% over the normal in lung and liver tissues respectively of tuberculous mice. 2. Concomitant with the increase in the NAD-glycohydrolase activity, the NAD-isonicotinic acid hydrazide-exchange activity also is increased in infection. The isonicotinic acid hydrazide analogue of NAD formed by the lung enzyme from tuberculous mice ha...
متن کاملNicotinamide-adenine dinucleotide glycohydrolase of Mycobacterium tuberculosis H37Rv.
The enzyme NAD glycohydrolase (EC 3.2.2.5) catalyses an exchange reaction between NAD and added free nicotinamide or other structurally related compounds, in addition to the hydrolytic cleavage of oxidized nicotinamide-adenine nucleotides (Zatman, Kaplan & Colowick, 1953; Zatman, Kaplan, Colowick & Ciotti, 1954). This type of exchange reaction results in the formation of a structural analogue o...
متن کاملMeasurement of nicotinamide adenine dinucleotide & nicotinamide adenine dinucleotide phosphate in tomato leaves.
As part of an investigation of the growth of tomato plants supplied with either nitrate or ammonium nitrogen (6), leaves were assayed for NAD4 and NADP. Anderson and Vennesland (1) assayed NAD and NADP in various green tissues and reported recoveries between 50 % and 85 % of NAD and NADP added to spinach leaf extracts. Very low levels of NAD and NADP were recorded for tomato leaf extracts. Thes...
