EC 1.10.3.14 is Orphan !
Common name :Ubiquinol oxidase (electrogenic, non H(+)-transporting)

Systematic name :Ubiquinol:O(2) oxidoreductase (electrogenic, non H(+)-transporting)

Other names :Cytochrome bd-I oxidase
CydA (gene name)
CydB (gene name)
Comments :This terminal oxidase enzyme is unable to pump protons but generates a proton motive force by transmembrane charge separation resulting from utilizing protons and electrons originating from opposite sides of the membrane to generate water. The bioenergetic efficiency (the number of charges driven across the membrane per electron used to reduce oxygen to water) is 1. The bd-I oxidase from the bacterium Escherichia coli is the predominant respiratory oxygen reductase that functions under microaerophilic conditions in that organism. cf.
