1.8.98.5 coenzyme F430 - 1.8.98.5 CoM-S-S-CoB disulfide reduction of CO2 by H2 is greatly stimulated by the CoM-S-S-CoB disulfide 1.8.98.5 additional information high concentrations of phosphate buffer are required for optimal FBEB activities in vitro, which because they promote hydrophobic protein-protein interactions between the inserted ferredoxin domain on HdrA and Fd 1.8.98.5 potassium phosphate - 1.8.98.5 potassium phosphate complex is most active in presence of 1.6 M potassium phosphate
