ubiquinol oxidase (electrogenic, non H+-transporting)
Cat No.
EXWM-0480
Description
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).
Form
Liquid or lyophilized powder
Enzyme Commission Number
EC 7.1.1.7 (Formerly EC 1.10.3.14)
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
cytochrome bd-I oxidase; cydA (gene name); cydB (gene name); ubiquinol:O2 oxidoreductase (electrogenic, non H+-transporting)
Reaction
2 ubiquinol + O2 + 4 H+[side 1] = 2 ubiquinone + 2 H2O + 4 H+[side 2]
