Abstract:
Electron paramagnetic resonance and circular dichroism spectra of cytochrome b(561) from chromaffin granule membranes indicated a 2:1 stoichiometry of high- and low-potential hemes. Recombinant bovine cytochrome b(561) expressed in a baculovirus system retained native spectroscopic characteristics and represents a promising model for further study.
