Pamlea J. Nelson, Gary E. Dean, Peter S. Aronson, and Gary Rudnick* abstract: Sodium ion dependent glutamate transport into rabbit renal brush border membranevesicles is stimulated by low external pH and inhibited by low internal pH. Imposition of a pH difference ()(interior alkaline) across the vesicle membrane drives glutamate accumulation in the absence of other driving forces. This process requires Na+ but is not due to generation of an Na+ gradient in response to. Internal K+ stimulates both the rate and extent of glutamate accue dicarboxylic amino acid glutamate is the substrate for specific transport systems in kidney and brain. In brain, the action of glutamate as a neurotransmitter is believed to be terminated by rapid and efficient reuptake into presynaptic nerve terminals (Curtis et al., 1960). Brain slices and sy-naptosomes accumulateglutamate by a high-affinity process (Navon & Lathja, 1969; Balear & Johnson, 1972; Logan & Snyder, 1972; Wheeler & Hollingsworth, 1978) that has also been studied in cultured cerebellarcells (Stallcup et al., 1979) and in isolated synaptic plasma membrane vesicles (Kanner & Sharon, 1978; Kanner & Marva, 1982). In the kidney, glutamate (like other amino acids) is freely filtered and ex-tensively reabsorbed in the proximal convoluted tubule (Weber, 1962). Glutamate is rapidly transported into intact proximal tubule epithelial cells (Siebernagl et al., 1975; Samarzija &
