Putidaredoxin, voltammetry

Apart from the above techniques, the electromodulated reflectance spectroscopy combined with cyclic voltammetry has been utilized by Gaigalas et al. [14] in the investigations of electron transfer between the 2Fe-2S protein putidaredoxin and either bare or bekanamycin-modified Ag electrode. Of the two models considered, the free diffusion model, as compared to the adsorbed layer model, exhibited better concordance with the experimental data. After modification of the Ag electrode with bekanamycin, it exhibited only a small increase in the observed redox reaction... 

Cytochromes c, Cy and gave chemically reversible voltammograms in phosphatidylcholine-cholesterol-lauric acid films [51-53]. Spinach ferredoxin (an iron-sulfur protein) in films of DDAB, phosphatidylcholine-cholesterol doped with dodecylamine, or dioctadecyldimethylammonium bromide also gave reversible voltammetry [54,55]. Chlorella ferredoxin gave reversible voltammograms in films of synthetic surfactants [56,57], bnt these films were not as stable as the heme-protein surfactant films. Iron snlfnr protein putidaredoxin gave qna-sireversible voltammetry in DDAB films [58].
