Redox loops and proton pumps [PDF]

open access: yesFEBS Letters, 1988
In a Review‐Hypothesis, Mitchell [(1987) FEBS Lett. 222, 235–245] has recently suggested possible molecular mechanisms for proton translocation by cytochrome oxidase. In describing these mechanisms, he extended his own concept of a redox loop in a manner expected to lead to confusion.

Electrogeneicity of the lysosomal proton pump

open access: yesFEBS Letters, 1984
Using acridine orange as a pH gradient probe, the effects of valinomycin and FCCP on the pH gradient across lysosomal membranes in an ATP‐free medium as well as on the rate of the inward ATP‐driven proton translocation were investigated. Both lysosome‐enriched and highly purified lysosomal preparations from rat liver were used with identical results ...
