ubiquinol oxidase (electrogenic, non H+-transporting) Quick inquiry Where to buy Suppliers range	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. EC 1. 10. 3. 10, ubiquinol oxidase (H+-transporting). ubiquinol oxidase (electrogenic, non H+-transporting) Group: Enzymes. Alternative Name: cytochrome bd-I oxidase; cydA (gene name); cydB (gene name); ubiquinol: O2 oxidoreductase (electrogenic, non H+-transporting).

ubiquinol oxidase (H+-transporting) Quick inquiry Where to buy Suppliers range	Contains a dinuclear centre comprising two hemes, or heme and copper. This terminal oxidase enzyme generates proton motive force by two mechanisms: (1) transmembrane charge separation resulting from utilizing protons and electrons originating from opposite sides of the membrane to generate water, and (2) active pumping of protons across the membrane. The bioenergetic efficiency (the number of charges driven across the membrane per electron used to reduce oxygen to water) depends on the enzyme; for example, for the bo3 oxidase it is 2, while for the bd-II oxidase it is 1. cf. EC 1. 10. 3. 14, ubiquinol oxidase (electrogenic, non H+-transporting). ubiquinol oxidase (H+-transporting) Group: Enzymes.
