Axial ligation and stoichiometry of heme centers in adrenal cytochrome b561.

Biochemistry - 24 Jul 2007

Kamensky Yury, Liu Wen, Tsai Ah-Lim, Kulmacz Richard J, Palmer Graham

Abstract excerpt

Cytochrome (cyt) b561 transports electrons across the membrane of chromaffin granules (CG) present in the adrenal medulla, supporting the biosynthesis of norepinephrine in the CG matrix. We have conducted a detailed characterization of cyt b561 using electron paramagnetic resonance (EPR) and optical spectroscopy on the wild-type and mutant forms of the cytochrome expressed in insect cells. The gz = 3.7...
