After crystalization, soaked, under anaerobic conditions, in 20 mM dithionite for 10 minutes, and washed with anaerobic buffer. Reduced crystals were sealed in an air-tight bomb and pressurized at ~1500 psi O2 for up to 10 minutes. Crystals were harvested and cryocooled after a brief soak in 50% PEG 400 supersaturated with O2.
