Structure-Function Relationship Studies of the Rhodobacter Sphaeroides Cytochrome AA(3)
… c oxidases. The role of a putative proton channel identified in the X-ray crystal structure of the cytochrome c oxidases from bovine heart mitochondria and P. denitrificans has been studied using site-directed mutagenesis coupled with a variety of biophysical characterization methods. Based …

The interactions of cytochrome bo3 from Escherichia coli with its substrates - ubiquinone and oxygen
Heme-copper respiratory oxygen reductases reduce O2 to water and use the redox free energy to generate the proton motive force. Among the heme-copper oxygen reductases are the quinol oxidases, which catalyze the 2-electron oxidation of ubiquinol or menaquinol instead of cytochrome c. Escherichia …
