“Adenosine deaminase is an aminohydrolase that converts adenosine to inosine and is thus involved in the catabolism of purine bases.”

“Uric acid is a byproduct of the metabolism of purine, a protein found particularly in red meat and offal, game, seafood and alcoholic drinks.”

“Conversely, the reaction of purine and pyrimidine nucleobases with alkylating and oxidizing agents generally results in site-specific cleavage.”

“This is the enzyme responsible for converting adenosine to inosine in the catabolism of the purines.”

“In comparison with the deamination of cytosine to uracil, the deamination of DNA purines is a minor reaction.”

“This view was reinforced by the elucidation of Z DNA and Z RNA structures, where the syn purines are mostly guanines.”
