Abstract excerpt

Pathways of proton entry have been identified in the proton-translocating heme-copper oxidases, but the proton exit pathway is unknown. Here we report experiments with cytochrome bo3 in Escherichia coli cells that may identify the beginning of the exit pathway. Systematic mutations of arginines 4...
