Three Hypoxanthine Derivatives from the Marine Cyanobacterium Okeania hirsuta

Molbank
Three novel hypoxanthine derivatives (1–3) were obtained from the Okinawan cyanobacterium Okeania hirsuta. The structures of these compounds were elucidated mainly based on the spectroscopic data, including 1D and 2D NMR, as well as high-resolution mass ...

FLAVIN-HYPOXANTHINE DINUCLEOTIDE

THE JOURNAL OF VITAMINOLOGY, 1957
1. FHD was synthesized from FAD by deamination with nitrous acid and the product was first isolated as barium salt. The yield and purity were, however, unsatisfactory by this method. Therefore, the product was extracted with cresol, followed by transfer in aqueous phase, and by subjecting to column chromatography, FHD was obtained in high purity in ...

Rhizosphere metabolite-mediated soil enhancement: long-term biochar application optimizes continuous soybean production systems

Biochar
Biochar offers promising solutions for agricultural sustainability, yet the intricate mechanisms governing rhizosphere metabolite-microbe-soil interactions remain poorly understood. Through a decade-long field experiment, the effects of sustained biochar

Hypoxanthine uptake by human erythrocytes [PDF]

FEBS Letters, 1979
It is well established that the uptake of hypoxan- thin, by human erythrocytes is mediated by its incorporation into IMP [ 11. The synthesis of this nucleotide is dependent on the intracellular availability of 5phosphoribosyl o-1-pyrophosphate (PRPP) and on the activity of hypoxanthine-guanine phospho- ribosyltransferase (HGPRT) [ 11.

Human hypoxanthine-guanine phosphoribosyltransferase.

Journal of Biological Chemistry, 1983
A mutant form of human hypoxanthine-guanine phosphoribosyltransferase (HPRTToronto) was isolated from erythrocytes of a male patient with gout due to a partial deficiency of enzyme activity. The tryptic peptides of HPRTToronto were mapped by reverse-phase high pressure liquid chromatography in an attempt to define the precise abnormality in its primary
