Title
Axial ligation of the high-potential heme center in an **Arabidopsis** cytochrome b561
Author
Abstract
Arabidopsis has four putative, di-heme cytochrome b561 proteins, including one localized in the tonoplast (TCytb). From a comparative electron paramagnetic resonance (EPR), UVVis absorption and resonance Raman study, on wild type, H83A/H156A-TCytb and H83L/H156L-TCytb double mutants, it follows that the H83 and H156 residues are binding one of the two hemes. These measurements show that the high-potential heme site is situated at the cytoplasmic side of the membrane and allow the unambiguous differentiation between two models on the heme localization in cytochrome b561 proteins.
