Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, SITTING DROP 7 283.15 Fe-hydrogenase holoenzyme from Methanolacinia paynteri was crystallized under 95%N2/5%H2 at 8 degree Celsius using a 96-well two-drop MRC crystallization plates. 0.7 ul of 25 mg/ml reconstituted enzyme with an Fe(II)-complex mimicking the FeGP cofactor and GMP (2mM final) was mixed with 0.7-ul reservoir solution under yellow light and incubated under dark conditions. The best crystal appeared within one month in 20% w/v polyethylene glycol 3350 and 200-mM magnesium formate reservoir solution (JBScreen Wizard 3&4 HTS, Jena Bioscience). The cryo protection was performed by adding 30% glycerol final to the crystallization solution.
