pubmed:abstractText |
The rates of p-aminohippurate (PAH) and of uric acid uptake by basolateral membrane vesicles isolated from proximal tubules of rat kidney have been investigated. Accumulation of both substrates against the concentration gradient within the vesicles was shown to occur in the presence of alpha-ketoglutarate (alpha-KG) and Na+ gradient in the incubation medium. The mechanism of the coupling between Na(+)-dicarboxylate symport and organic anion transport is discussed based on the differences between the rates of PAH and of uric acid uptake. It is proposed that the limiting step of coupling between two transporters is the step of alpha-KG-organic anion exchange.
