The natural occurrence of cyclic nucleotides in higher plants, formerly a topic of fierce debate, is now established, as is the presence of nucleotidyl cyclases and cyclic nucleotide phosphodiesterases capable of their synthesis and breakdown. Here we describe the significant properties of cyclic nucleotides, also outlining their second messenger ...

Publisher Summary This chapter discusses the synthesis and degradation of nucleotides. A nucleotide consists of a purine or pyrimidine base, a pentose, and a phosphate. Nucleotides are synthesized by two types of metabolic pathways: de novo synthesis and salvage pathways.

A supply of ribonucleoside and deoxyribonucleoside 5′-triphosphates is required for the biosynthesis of nucleic acids (chapters 6 and 8). The synthesis of these compounds occurs in two main stages: (1) the formation of the purine and pyrimidine ring systems and their conversion into the parent ribonucleoside monophosphate, inosine 5′-monophosphate (IMP)

The separation of nucleotides by isotachophoresis
Journal of Chromatography A, 1972The mono-, di-, and triphosphates of adenosine, cytidine, guanosine, and uridine were sepd. by isotachophoresis in several different electrolyte systems. At lower pH, the differences in step-height were greater, and complete sepn. of a mixt.

Reduction of cytidine nucleotides to deoxycytidine nucleotides by mammalian enzymes
Biochimica et Biophysica Acta, 1962Abstract 1. 1. Conditions for the reduction in vitro of cytidine nucleotides to deoxycytidine nucleotides by an extract of the Novikoff ascites rat tumor are described. ATP was required; TPN, Mg 2+ and Fe 3+ stimulated the reaction. The effects of other metal ions and of a number of organic compounds on the reaction are described. 2.
