  • Title: Effect of pyocin R1 on the glucose metabolism of sensitive cells of Pseudomonas aeruginosa.
    Author: Kageyama M.
    Journal: J Biochem; 1978 Dec; 84(6):1373-9. PubMed ID: 104980.
    Abstract:
    The effect of pyocin R1 on the glucose metabolism of sensitive Pseudomonas cells was investigated. Upon treatment with pyocin R1, although the rate of O2 uptake of the sensitive cells for glucose or gluconate was not very much affected at first, the final level of O2 uptake was greatly reduced. When 2-oxogluconate was used as a substrate, O2 uptake was immediately halted by pyocin. By determining the amounts of glucose, gluconate, and 2-oxogluconate before and after the reaction and the amount of O2 consumed, it was concluded that glucose was exclusively metabolized via the following pathway with quantitative accumulation of 2-oxogluconate after pyocin treatment. (Formula: see text). The possible mechanism of this change is discussed.
