REMARK 280 CRYSTALLIZATION CONDITIONS: CRYSTALLIZATION OF [FE]-HYDROGENASE      
REMARK 280  -METHENYL-H4MPT+ COMPLEX WAS PERFORMED IN THE ANAEROBIC TENT        
REMARK 280  WITH GAS PHASE 100%N2 AT ROOM TEMPERATURE UNDER DARK CONDITION.     
REMARK 280  THE RECONSTITUTED [FE]-HYDROGENASE HOLOENZYME (50 MG/ML) WAS        
REMARK 280  MIXED WITH 10 MM METHENYL-H4MPT+, BOTH OF WHICH CONTAINED 10 MM     
REMARK 280  MOPS/KOH PH 7.0. THE FINAL CONCENTRATIONS OF [FE]-HYDROGENASE       
REMARK 280  AND METHENYL-H4MPT+ WERE 24 MG/ML AND 3 MM, RESPECTIVELY. AFTER     
REMARK 280  INCUBATING THE MIXTURE IN THIS TENT UNDER DARK CONDITION FOR 5      
REMARK 280  MIN, THE ENZYME SOLUTION WAS CENTRIFUGED AT 8000 RPM FOR 5 MIN      
REMARK 280  BY USING CENTRIFUGAL FILTERS MADE OF POLYVINYLIDENE FLUORIDE        
REMARK 280  (PVDF, MILLIPORE). THE CRYSTALLIZATION SOLUTION CONTAINED 20% W/    
REMARK 280  V POLYETHYLENE GLYCOL 3350 AND 200 MM SODIUM THIOCYANATE WITH A     
REMARK 280  RATIO OF PROTEIN MIXTURE AND CRYSTALLIZATION RESERVOIR OF 2 UL /    
REMARK 280  2 UL DROPS SPOTTED ON A 24 WELL JUNIOR CLOVER PLATE. THE CRYSTAL    
REMARK 280  WAS SOAKED FOR A COUPLE OF SECONDS IN 20% W/V POLYETHYLENE          
REMARK 280  GLYCOL 3350, 20% V/V GLYCEROL AND 200 MM SODIUM THIOCYANATE
