Enzymatic synthesis of nucleoside diphosphates and triphosphates.
It has been recognized from recent studies that nucleoside triphosphates, other than ATP,’ function in biologic systems as phosphorylating agents (1) and in coenzyme synthesis (2) in a manner analogous to that of ATP. The discovery of the natural occurrence of a variety of purine and pyrimidine nucleoside diand triphosphates (3-5) and the likelihood that new biologic functions for these nucleot...
متن کاملPhosphorylation of Pyrimidine Deoxynucleoside Analog Diphosphates
D-Nucleoside analogs, which are in the natural configuration, as well as the L-nucleoside analogs, are clinically relevant antiviral and anticancer agents. Metabolism of L-nucleoside analog diphosphates to the triphosphates, however, remains unexplored. Studies with recombinant nm23-H1 and -H2 isoforms indicated that L-nucleoside analog diphosphates were not phosphorylated by their nucleoside d...
متن کاملNucleoside 5'-diphosphates as effectors of mammalian ribonucleotide reductase.
It was found that nucleoside 5'-diphosphates could serve as effectors of ribonucleotide reductase. ADP was an activator of CDP reduction; ADP reduction was activated by dGDP; GDP reduction was activated by dTDP. Conversely, dADP inhibited the reduction of CDP, UDP, GDP, and ADP; dGDP inhibited UDP and GDP reductions; and dTDP inhibited UDP reduction. The inhibition of UDP reduction by dADP, dTD...
متن کاملEnzymatic phosphorylation of butyrate.
Conservation of thiol ester bond energy through a reaction sequence involving phosphorolysis of acetyl coenzyme A by phosphotransacetylase (1, 2) and the subsequent formation of adenosine triphosphate from adenosine diphosphate and acetyl phosphate by acetokinase (3, 4) is well established in fermentative bacteria. A similar reaction sequence involving butyryl coenzyme A, phosphotransbutyrylase...
متن کاملEnzymatic phosphorylation of acetate.
The metabolic utilization of acetate (oxidation via the citric acid cycle, synthesis of higher fatty acids, cholesterol, and possibly other compounds) requires a preliminary activation through conversion to acetyl C0A.l Two main mechanisms are known to bring about this activation (2). One of these mechanisms, utilized by animal tissues, yeast, and some bacteria, seems to involve a single enzyme...
