X-band EPR spectra of cytochrome b6f complex from Nostoc for parallel and perpendicular orientations of the microwave magnetic field. Purified b6f complex was diluted to a concentration of 0.105 mm in TNE buffer supplemented with 1 mm UDM and 300 mm sucrose. Experimental conditions: microwave frequency, 9.65 GHz (B1 ⊥ B) and 9.37 GHz (B1 ∥ B); microwave power, 2 milliwatts (B1 ⊥ B) and 0.2 milliwatt (B1 ∥ B).
