Surface-coupled proton exchange of a membrane-bound proton acceptor [PDF]

Proceedings of the National Academy of Sciences, 2010
Proton-transfer reactions across and at the surface of biological membranes are central for maintaining the transmembrane proton electrochemical gradients involved in cellular energy conversion. In this study, fluorescence correlation spectroscopy was used to measure the local protonation and deprotonation rates of single pH-sensitive ...

Membrane sodium-proton exchange and primary hypertension. [PDF]

Hypertension, 1993
Recent studies have revealed that an enhancement of sodium-proton exchange is a frequently observed ion transport abnormality in essential hypertension. An altered antiport activity not only is measurable in blood cells of hypertensive subjects ex vivo but also is detectable in skeletal muscle in vivo. Several lines of argument suggest that the altered
