Inhibition effects of cyanide on Psa CcP electrocatalysis at pH 7. (A) Raw data of electrocatalytic reduction of 25 μM substrate (solid line) in the presence of 10 (dashed line), 80 (dot-dashed line), 250 (short dash line) and 500 μM (dotted line) potassium cyanide. (B) Dixon plot of cyanide addition in the presence of 15 μM (λ) and 25 μM (σ) hydrogen peroxide.
