Figure 4From: Semi-rational engineering of cellobiose dehydrogenase for improved hydrogen peroxide productionVerification of protein purity. A. SDS-PAGE of CDHs expressed in P. pastoris after purification. Lane 1, molecular mass marker; lane 2, r CDH; lane 3, variant N700S. B. Absorption spectra of the CDH variant N700S. The black line shows the oxidized state and the grey line the reduced form. The difference spectrum (red-ox) is shown in the inset.Back to article page
