Light–Nucleotide versus Ion–Nucleotide Interactions for Single-Nucleotide Resolution
The Journal of Physical Chemistry B, 2021Several parallel reads of ionic currents through multiple CsgG nanopores provide information about ion-nucleotide interactions for sequencing single-stranded DNA (ss-DNA) using base-calling algorithms. However, the information in ion-nucleotide interactions seems insufficient for single-read nanopore DNA sequencing.

Journal of Parenteral and Enteral Nutrition, 1999
Background: Dietary nucleotides play an important role in the growth and development of the intestine. Parenteral supplementation of nucleic acids may be necessary to maintain the mucosal proliferation and barrier functions during parenteral nutrition (PN). Methods: Male Wistar rats were divided into 3 groups: FED (food ad libitum with saline infusion);

Nature, 1976
It is show that in aqueous solution the backbone conformation of adenosine is as much flexible as that of 3'-AMP, 5'-AMP and 3', 5'-ADP indicating that nucleotides are not any more rigid than nucleosides. The flexible conformation of the monomeric components is conserved in the nucleotidyl units of destacked ApA, ApApA and poly(A), but it is not ...

Current Opinion in Neurobiology, 1997
Adenosine 5'-triphosphate (ATP) and/or related nucleotides act at both ionotropic (P2X) and metabotropic (P2Y) receptors. P2X receptor subunits (P2X1-P2X7) form ligand-gated cation channels, as homomultimers or heteromultimers. Recent work indicates that P2X3 subunits participate in channels expressed by nociceptive sensory neurons, and that the second

Phytochemistry, 2004
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 ...

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.

Nucleotides and nucleotide derivatives as signal molecules in plants
Journal of Experimental BotanyAbstract 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 ...
