Zinc uptake by proximal cells isolated from rabbit kidney: Effects of cysteine and histidine

Abstract

The aim of this study was to characterize the mechanisms of zinc transport in proximal cells isolated from rabbit kidney cortex. Uptakes of 65Zn were assessed under initial rate conditions, after 0.5 min of incubation. The kinetic parameters obtained at 20°C were a K m of 15.0±1.5 μM, a J max of 208.0±8.4 pmol min−1 (mg protein)−1, and an unsaturable… (More)
