| + | ''E. coli'' bd oxidase is made up of four individual subunits. The two major subunits, CydA and CydB, are each composed of one peripheral helix and two bundles of four transmembrane helices. The <scene name='83/837228/Cyda/3'>CydA subunit</scene> plays the most important role in the oxygen reduction reaction as it contains the Q-loop as well as all three heme groups. The <scene name='83/837228/Cydb/1'>CydB subunit</scene> harbors the ubiquinone molecule which provides structural support to the subunit that mimics the three hemes found in CydA. The remaining two subunits, CydS and CydX, are both single helix structures that assist in the oxygen reduction reaction. Unique to ''E. coli'', the <scene name='83/837228/Cyds/1'>CydS subunit</scene> binds to CydA to block oxygen from directly binding to heme b595. The <scene name='83/837228/Cydx/1'>CydX subunit</scene> promotes the assembly and stability of the oxidase complex. | ||
