摘要：

The pattern of metabolism of soluble purines infiltrated into pea seedlings has been investigated. Nucleotides were converted to the corresponding nucleosides and free bases. Nucleosides were converted to the corresponding free bases. Deamination of the adenine series of compounds to the hypoxanthine series occurred at nucleotide level. Oxidation of the hypoxanthine series of compounds to the xanthine series took place at free base level, providing strong evidence for the presence of xanthine oxidase (xanthine: O2 oxido-reductase, EC 1.2.3.2) in these seedlings. Sub-cellular fractions from pea seedlings were prepared and tested for activity against nucleotide substrates. Hydrolytic degradation of these nucleotides by the soluble cell fraction was observed, but all particulate fractions were inactive. The possible intracellular compartmentalization of endogenous purine derivatives is discussed. © 1969.
