Abstract:
:Plasmalemma redox activity in the diatom Thalassiosira is competitively inhibited by antiserum prepared against algal nitrate reductase (NR), and fluorescent labeling experiments reveal the binding of NR antiserum to the cell surface. Furthermore, the external electron acceptor Cu bathophenanthroline disulfonate causes immediate inhibition of intracellular primary amine production. A model is proposed in which plasmalemma-bound nitrate reductase reduces extracellular electron acceptors and intracellular nitrate and also acts as a trans-plasmalemma proton pump.
