  • Title: Phosphorylase-mediated mobilization of the amino group of adenine in Bacillus cereus.
    Author: Mura U, Di Martino D, Leporini C, Gini S, Camici M, Ipata PL.
    Journal: Arch Biochem Biophys; 1987 Dec; 259(2):466-72. PubMed ID: 3122663.
    Abstract:
    Mobilization of the ribose moiety of purine nucleosides as well as of the amino group of adenine may be realized in Bacillus cereus by the concerted action of three enzymes: adenosine phosphorylase, adenosine deaminase, and purine nucleoside phosphorylase. In this pathway, ribose-1-phosphate and inorganic phosphate act catalytically, being continuously regenerated by purine nucleoside phosphorylase and adenosine phosphorylase, respectively. As a result of such a metabolic pathway, adenine is quantitatively converted into hypoxanthine, thus overcoming the lack of adenase in B. cereus.
