  • Title: Energetics of renal Na+ and H+/L-alanine co-transport systems.
    Author: Jessen H, Vorum H, Jørgensen KE, Sheikh MI.
    Journal: Biochem J; 1988 Nov 15; 256(1):299-302. PubMed ID: 2851984.
    Abstract:
    The stoichiometric properties of Na+- and H+-dependent L-alanine transporters recently identified in luminal-membrane vesicles prepared from proximal convoluted tubules (pars convoluta) and proximal straight tubules (pars recta) of rabbit kidney were studied. We provide indirect evidence suggesting that one Na+ and one H+ ion are co-transported with the L-alanine molecule via Na+-dependent and H+-dependent transport systems located in vesicles from pars convoluta. Furthermore, our experimental data suggest that both the high-affinity and the low-affinity Na+-dependent L-alanine transport systems of pars recta vesicles operate with a 1:1 stoichiometry.
