| pubmed-article:2917162 | pubmed:abstractText | The characteristics of uridine transport were studied in rabbit intestinal brush-border membrane vesicles. Uridine was taken up into an osmotically active space in the absence of metabolism and there was no binding of uridine to the membrane vesicles. Uridine uptake was markedly enhanced by sodium, but showed no significant stimulation by other monovalent cations tested. Kinetic analysis of the sodium-dependent component of uridine flux indicated a single system obeying Michaelis-Menten kinetics (Km value of 6.4 +/- 1.4 microM with a Vmax of 9.1 +/- 3.6 pmol/mg protein per s as measured under zero-trans conditions with a 100 mM NaCl gradient at 24 degrees C). A variety of purine and pyrimidine nucleosides were able to inhibit sodium-dependent uridine transport, suggesting that these nucleosides are also permeants for the same system. Consistent with this suggestion was the finding that these nucleosides also stimulated uridine efflux from the brush-border membrane vesicles. The sodium: uridine coupling stoichiometry was found to be 1:1 as measured by the activation method. From these results it is concluded that a broad specificity sodium-dependent nucleoside transporter is present at the brush-border membrane surface of rabbit enterocytes. | lld:pubmed |
