title: [Incorporation of S-adenosylmethionine in the isolated and perfused rat liver. Preliminary study].
abstract: The uptake of labeled S-adenosylmethionine (SAM) by isolated and perfused rat liver has been compared to that of methionine: the rate of incorporation of the amino acid exceeds by about three times that of the sulfonium compound. S-Adenosylmethionine transport system shows saturation kinetics with an apparent Km of 59,5 microM and is energy-dependent, as demonstrated by the inhibition by 2,4-dinitrophenol.
