Height distribution was found to be the same for the wt and K27C azurins, while the height of S118C is 5 - 8 Å lower AFM permits to distinguish between the “standing” and the “lying” azurin molecules. Electrochemical characteristics of the azurin monolayers. Half wave potential is defined as (E pa –E pc )/2 vs. SCE Azurin WT Azurin K27C Azurin S118C E 1/2 * (mV vs. SCE)165–175165–175120–145 k et /s –1 300–400210–320300–570 BUT: the electron transfer rate is independent of the distance between the Cu and the electrode surface Is it possibly an effect of heterogeneous binding?
