title: [Influence of the age on 5'-nucleotidase activity associated with the rat liver plasma membrane].
abstract: The influence of age on the isothermic and temperature-induced kinetics of the plasma membrane 5'-nucleotidase was studied in rat liver. The apparent Km values increased with age, while the Vmax, the temperature discontinuity and the Ex above and below the max break were unaffected.
