Hypoxanthine nucleotides and muscular contraction
Biochimica et Biophysica Acta, 1963Abstract 1. 1. Experiments have been devised to test the suggestion of a number of investigators that the interconversion of adenine and hypoxanthine nucleotides may provid the energy for muscular contraction. 2. 2. Several methods for the assay of very small amounts of these nucleotides in muscle extracts have been examined.

Summary Transport of purine bases and nucleosides by a variety of mammalian cell lines is generally accomplished by facilitated diffusion, a non-concentrative, saturable process. However, previous investigators have been unable to detect a saturable component for the transport of hypoxanthine by human fibroblasts deficient in hypoxanthine-guanine ...

Tautomeric Polymorph of Hypoxanthine from a Tautomeric Amorphous Hypoxanthine Precursor
Crystal Growth & DesignAbstract The nonclassical crystallization processes via amorphous precursors are one of the important principles in the organic biomineralization of guanine. Hypoxanthine is the second component in guanine biominerals. Amorphous hypoxanthine was synthesized for the first time via a neat ball-milling method, and a novel hypoxanthine ...

A xanthine oxidase (XOD) from buttermilk was immobilized covalently onto boronic acid functionalized gold coated iron nanoparticles (Au@FeNPs) electrodeposited on pencil graphite (PG) electrode, via the boroester linkages, between free hydroxyl groups of boronic acid, α-COOH and -NH2 groups of enzyme.

Exercise and Sport Sciences Reviews, 2015
Cardiorespiratory and biochemical indicators typically used by contemporary elite athletes seem to have limited applicability. According to some recent studies, purine metabolism better reflects exercise response and muscle adaptation in this group.

The Spectrum of Hypoxanthine-guanine Phosphoribosyltransferase Deficiency
QJM: An International Journal of Medicine, 1973Abstract The spectrum of clinical manifestations of hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) deficiency is presented by reference to eight patients from five kindred. These patients illustrate the range of associated neurological findings, together with the variety of presentation and complications due to the ...

Uptake of Hypoxanthine in Human Erythrocytes
1977The concentration of oxypurines in the plasma is known to be rather low (10 – 40 μM) (6). Since the formation of purines is accomplished to a great extent by the liver (7, 8), a transport of purines by erythrocytes from liver to tissues with limited or no capacity of de novo purine synthesis has been postulated (1, 3).

Hypoxanthine transport in human erythrocytes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1967Abstract Using rapid sampling by filtration, it has been possible to follow and describe the transport of hypoxanthine across the human red blood cell membrane. The dependence of the transport rate upon the concentration of hypoxanthine is complex, and suggests a two-component mechanism. The first is a “saturable carrier system” with a K m of 0.

Isotope exchange between hypoxanthine and both inosinate and guanylate, and between guanine and the same two ribonucleotides, support the view that hypoxanthine and guanine bind to the same site on hypoxanthine-guanine phosphoribosyltransferase.
