Type	Source	Accession Code	Details
experimental model	Other		MR was performed using a preliminary DMO structure. This early DMO structure was obtained largely using a high-redundancy, 1.5418 A wavelength data set for Fe single wavelength anomalous dispersion (SAD) phasing, with assistance from the sulfur anomalous signal in a high-redundancy, 2.29 A wavelength data set.

1	VAPOR DIFFUSION, SITTING DROP	5.5	294	The purified protein was concentrated to 10-20 mg/ml and buffer exchanged into 25 mM Tris-HCl, pH 8.0, 30-50 mM NaCl, 25 mM sodium citrate. DMO crystals were grown using the vapor diffusion by sitting drop method, with a reservoir solution of 8-11% PEG 6000, 100 mM sodium acetate buffer-pH 5.5, 1 M LiCl, and 4ul droplets of varying protein-to-precipitant ratios. To prepare a DMO-non-heme iron-dicamba crystal, some crystals were transferred to a cryo-amenable storage solution that contained 25 mM dicamba (12.3 % PEG6000, 95 mM sodium acetate pH 5.5, 21% glycerol, 1mM NaN3, and 25 mM dicamba) for 5-6 hours prior to plunge-cooling for cryo-storage and low temperature data collection. VAPOR DIFFUSION, SITTING DROP, temperature 294K
