Reduction of cytidine nucleotides to deoxycytidine nucleotides by mammalian enzymes

Biochimica et Biophysica Acta, 1962
Abstract 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.

Nucleotide und Nucleinsäuren

2002
Nucleotide wurden erstmals als Bausteine der Nucleinsauren gefunden. Sie sind in charakteristischer Weise aufgebaut und haben inzwischen einer ganzen Substanzklasse gleichermasen aufgebauter Verbindungen ihren Namen gegeben.

Nucleotides and nucleotide derivatives as signal molecules in plants

Journal of Experimental Botany
Abstract In reaction to a stimulus, signaling molecules are made, generate a response, and are then degraded. Nucleotides are classically associated with central metabolism and nucleic acid biosynthesis, but there are a number of nucleotides and nucleotide derivatives in plants to which this simple definition of a signaling molecule ...

Nucleotides as nucleophiles: Reactions of nucleotides with phosphoimidazolide activated guanosine

Origins of life and evolution of the biosphere, 1992
An earlier study of the reaction of phosphoimidazolide activated nucleosides (ImpN) in aqueous phosphate buffers indicated two modes of reaction of the phosphate monoanion and dianion. The first mode is catalysis of the hydrolysis of the P-N bond in ImpN's which leads to imidazole and nucleoside 5'-monophosphate.

A new adenine nucleotide

Biochimica et Biophysica Acta, 1953
Abstract A new nucleotide has been shown to be present in commercial samples of adenosine-5′-triphosphate (ATP). The analytical data suggest the structure adenosine-5′-tetraphosphate.

Profiling of Sugar Nucleotides

2017
Sugar nucleotides are essential building blocks for the glycobiology of all living organisms. Detailed information on the types of sugar nucleotides present in a particular cell and how they change as a function of metabolic, developmental, or disease status is vital.

Nucleotides

2015
: Nucleotides are phosphorylated nucleosides. A nucleoside is a combination of a nucleic acid base and a sugar. ATP is a nucleotide that participates in numerous energy transduction reactions. NTPs are the ultimate building blocks of nucleic acids. Nucleic acid polymerases are referred to as pols.
