  • Title: Arginine transport in mitochondria of Neurospora crassa.
    Author: Yu YG, Weiss RL.
    Journal: J Biol Chem; 1992 Aug 05; 267(22):15491-5. PubMed ID: 1386360.
    Abstract:
    Transport of arginine into mitochondria of Neurospora crassa has been studied. Arginine transport was found to be saturable (Km = 6.5 mM) and to have a pH optimum of pH 7.5. Mitochondrial arginine transport appeared to be facilitated transport rather than active transport because: (i) the arginine concentration within the mitochondrial matrix after transport was similar to that of the reaction medium, and (ii) uncouplers and substrates of oxidative phosphorylation did not affect the transport rate. The basic amino acids ornithine, lysine, and D-arginine inhibited arginine transport. The arginine transport system could be irreversibly blocked by treating mitochondria with the reactive arginine derivative, N-nitrobenzyloxycarbonyl-arginyl diazomethane.
