3.D.4.4.3
The proton pumping Caa3-type cytochrome oxidase chains A-F. The crystal structure (PDB: 2YEV) is known (2.36Å resolution; Lyons et al., 2012). It has a covalently teathered cytochrome c domain. In the cytochrome aa3, O2 molecules that arrive at the reduction site diffuse through the X-ray-observed tunnel, supporting its role as the main O2 delivery pathway in this cytochrome ba3 as well as the cytochrome aa3 of Rhodobacter spheroides (Mahinthichaichan et al. 2018).
