Amicyanin reduction potentials

Gray, K. A., Knaff, D. B., Husain, M., and Davidson, V. L., 1986, Measurement of the oxidation-reduction potentials of amicyanin and c-type cytochromes from Paracoccus denitrificans, FEES Lett. 207 39n242. [Pg.142]

Although the Cu(II) form of T. versutus amicyanin is stable down to pH 4, the reduced form begins to denature below pH 6.4 (63). An active site protonation of the Cu(I) protein similar to that of plastocyanin, but with pKa 7.18, affects the reduction potential. [Pg.395]

Fig. 7. Variation of the reduction potential (E°) of wild-type amicyanin with pH (/ = 0.10 M, NaCl). The values are obtained from cyclic voltammetry and are all referenced to the NHE at 22°C. The line shown is the fit to the following equation (.113) E° (pH) = E° (high pH) + (RT/nF) ln(l + [H"]/ifir ). Fig. 7.
