Complete Tracking of Proton Flow in Thylakoids the Unit Conductance of CF0 is Greater than 10 fsrtion of the ATP synthase (CF.) by EDTA treatment. Proton pumps were stimulated by short flashes of light. Proton flux through CF. was measured spectrophotometrically in three different ways: as proton efflux from the lumen (via neutral red), charge flow across the membrane (via electrochrom-ism) an

Essential Role of Arginine Residues in the Interaction of F, with F, in , ATP Synthasedria, chloroplasts and bacteria (for reviews, see refs. 1–3). Among these the ATP synthase complex of . has been most extensively characterized by both biochemical and genetic studies. As in all other ATP synthase systems, the . complex is composed of two entities: the F. sector is a peripheral prot

The Amplifying Transduction Cascade Triggered by Rhodopsin in Visual Receptor Cells Biochemical and nal or neuronal membrane receptors to their various intracellular effectors: AMP cyclase, phosphodiesterase or phospholipase specific for phosphatidylinositol hydrolysis. This analogy between the transducin cascade and the other G protein mediated processes had led a few years ago to the suggestion

Calcium and Guanosine Nucleotide Modulation of Melanotropin Receptor Function and Adenylate Cyclase eports have shown that millimolar levels of extracellular free calcium are important for both ACTH binding and subsequent corticosteroid secretion in rat adrenal cortical cells (Cheitlin ., 1985), and for photoaffinity labeling and subsequent melanophore dispersion in Xenopus, using photoreactive .-
