Abstract excerpt
Site-directed mutagenesis was used to investigate the mechanism of electron and proton transfer in the ubiquinol oxidase, cytochrome bo3, from Escherichia coli. The reaction between the fully reduced form of the enzyme and dioxygen was studied using the flow--flash method. After rapid mixing of C...
