a Surface representation of each intermediate state of the CcO at 1.9 Å (O), 2.6 Å (R), 1.9 Å (PCO), and 2.3 Å (F) resolution. Uv/visible absorption spectra were individually and consistently recorded (intermediate state minus O-state). The illustrated map densities are filtered to equal contour levels of 1. b Ribbon representation of all four subunits with corresponding cofactors of the CcO. Color scheme: SU I, blue; SU II, yellow; SU III, green; SU IV, red. The antibody fragment (Fv) and membrane scaffold protein (MSP) are shown as a white surface.
