  • Title: AMP metabolism in the marine bacterium Beneckea natriegens.
    Author: Pickard MA, Whelihan JA, Knowles CJ.
    Journal: Can J Microbiol; 1980 May; 26(5):633-6. PubMed ID: 6249477.
    Abstract:
    The catabolism of AMP by preparations from Beneckea natriegens has been reexamined. In the absence of ATP, cell-free extracts catabolized AMP via adenosine to inosine. When ATP was present, adenylate kinase converted AMP to ADP, lowering the rate of AMP catabolism. Particle-free supernatants (225,000 x g) metabolized AMP alone slowly, but adenylate kinase was active when ATP was added. Washed particulate fractions contained AMP nucleotidase activity which converted AMP to adenosine; in the presence of ATP, adenosine formation was reduced by residual adenylate kinase associated with the particulate fraction. IMP was not detected as a metabolite in these experiments.
