LITERATURE
KCl
activates HdrDE activity, best at 3 M KCl, about 50% activity at 2 and 4 M KCl. Formate oxidation by FdhGHI is slightly lower with 2 M KCl instead of NaCl
NaCl
activates FdhGHI activity, best at 2 M, formate oxidation is slightly lower with 2 M KCl instead of NaCl
additional information
at pH 7.5, the specific activity of HdrDE with 2 M potassium chloride is about 40% higher than with 2 M sodium chloride
