Analysis of Purine in Purine-Rich Cauliflower
Nucleosides, Nucleotides and Nucleic Acids, 2010 Purine is a general term for purine nucleotides, nucleosides, bases, and nucleic acid. The amount of purine nucleotides, nucleosides, and bases in purine-rich cauliflower was determined with the use of LC-MS and HPLC, and the ratio of these molecules were compared with in raw and in heated condition.

New insights into purine metabolism in metabolic diseases: role of xanthine oxidoreductase activity.
American Journal of Physiology. Endocrinology and Metabolism, 2020Xanthine oxidoreductase (XOR) consists of two different forms, xanthine dehydrogenase (XDH) and xanthine oxidase (XO), and is a rate-limiting enzyme of uric acid production from hypoxanthine and xanthine. Uric acid is the end-product of purine metabolism

On the relevance of hydroxyl radical to purine DNA damage
Free radical research, 2021Hydroxyl radical (HO•) is the most reactive toward DNA among the reactive oxygen species (ROS) generated in aerobic organisms by cellular metabolisms. HO• is generated also by exogenous sources such as ionizing radiations.

The biosynthesis of the purines
Ergebnisse der Physiologie Biologischen Chemie und Experimentellen Pharmakologie, 1959Of the many problems which confront the biologist in his understanding of the operations of the cell, the synthesis of biologically important substances is now the most amenable to solution. It has been the domain of the biochemist to probe into the integrated cellular system by dissembling its enzymatic machinery as a means of studying the complex ...

Purine Release, Metabolism, and Signaling in the Inflammatory Response.
Annual Review of Immunology, 2019ATP, NAD+, and nucleic acids are abundant purines that, in addition to having critical intracellular functions, have evolved extracellular roles as danger signals released in response to cell lysis, apoptosis, degranulation, or membrane pore formation ...

GAR transformylase, which is responsible for the incorporation of formate carbon into what becomes position 8 of the purine ring, has been completely separated from 5-amino-4-imidazolecarboxamide ribotide transformylase (3). The latter enzyme is responsible for the incorporation of formate carbon into position 2 of the purine ring.

Photochemistry and Photobiology, 1988
Abstract— DNA purine modifications by ultraviolet irradiation have not been as extensively studied as those of pyrimidines. However, a number of such reactions have been identified. These include photochemical addition of amino acids, photoalkylation by alcohols, amines and other compounds, photochemical activation of procarcinogens to mutagenic ...

3 Purine, Purine Nucleoside, and Purine Nucleotide Aminohydrolases
1971Publisher Summary This chapter discusses the chemical significance of adenosine aminohydrolase, 5′-adenylic acid aminohydrolase, adenine nucleoside, nucleotide aminohydrolase, guanine aminohydrolase, and guanosine aminohydrolase. The partially purified adenine aminohydrolase from Azotobacter vinelandii catalyzes the anaerobic conversion of adenine ...
