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 ...

Analysis of Purine in Purine-Rich Cauliflower
Nucleosides, Nucleotides and Nucleic Acids, 2010Purine 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.

Biochemical Society Transactions, 1981
Abstract The inherited disorders of purine metabolism associated with renal disease are listed in Table 24.1. They are the sole cause of only a small proportion of all renal disease and are therefore best considered as part of the overall problem of purine, especially uric acid metabolism-related renal disease.

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 ...

Epilepsia, 1986
Summary: Developing antiepileptic agents that are specifically tailored to a patient's individual biochemistry has long been a goal of neurology. Three patients who had hyperuricosuria combined with a seizure disorder that failed to respond to traditional anticonvulsants are described. The patients had the best control of their seizure disorder when a

Feedback Control of Purine Biosynthesis by Purine Ribonucleotides
Nature, 1959IN recent years a number of biosynthetic sequences have been shown to be regulated by feedback mechanisms, which have been of two general types, the first involving regulation of the activity of an enzyme by an inhibitory effect of an end-product1,2, the second involving regulation of the rate of synthesis of an enzyme by negative-induction, or ...

Theoretical studies on the purine radical induced purine–purine type intrastrand cross-links
Organic & Biomolecular Chemistry, 2019Purine-type radicals can attack their 3′/5′ flanking purine deoxynucleosides forming the purine–purine type DNA intrastrand cross-links.
