Inosinic Acid Dehydrogenase Activity
ated in normal subjects and in patients with the LeschNyhan syndrome. A significant difference in activity was found between erythrocytes derived from normal controls (1.21±0.47 pmoles/hr per mg protein) and from 15 patients with the Lesch-Nyhan syndrome (6.72 ±6.23 pmoles/hr per mg protein). However, no difference in activity was demonstrable in muscle or leukocytes derived from normal and Les...
متن کاملLead Content of Foodstuffs
The lead content of a number of foodstuffs, particularly baby fruit juices and milk, is reported. Samples were analyzed in quadruplicate by using an automated Delves cup atomic absorption procedure. A large proportion of the products examined contained significant amounts of lead. Of 256 metal can examined, the contents of 62% contained a lead level of 100 mug/l. or more, 37% contained 200 mug/...
متن کاملInosinic acid dehydrogenase of sarcoma 180 cells.
Inosinic acid dehydrogenase was partially purified from sarcoma 180 cells. The concentrations of each reactant, inosine 5’-phosphate, nicotinamide adenine dinucleotide, and K+, altered both the apparent K, and Vmaxvalues for each of the other reactants. Enzymatic activity was inhibited by both products of the reaction, xanthosine S-phosphate and reduced nicotinamide adenine dinucleotide; the in...
متن کاملCopolymers of Adenylic Acid with Inosinic and Cytidylic Acids
In earlier publications the molecular properties of copolymers of adenylic and uridylic acids have been described (1, 2). In brief, evidence was obtained for the occurrence of ordered regions, probably of a helical character, which persisted for copolymers containing quite high uridylic contents. Although collectively accounting for a large portion of the molecule, these regions of order were a...
متن کاملPurification and Properties of Inosinic Acid llehydrogenase from E’scherichia coZi*
Inosinic acid dehydrogenase was prepared from a derepressed mutant of Escherichia coli. Although the reaction catalyzed formally resembles those catalyzed by chicken liver xanthine dehydrogenase and related enzymes, this enzyme is devoid of any flavin, iron complex, or molybdenum component, and the kinetics indicate necessity for concomitant binding of substrate and DPN. The enzyme is absolutel...
