摘要: Membrane preparations from Synechococcus 6301 and 6311 exhibited low-temperature electron paramagnetic resonance (EPR) spectra in the g = 2.08 region characteristic of copper. The physical parameters power-saturation characteristics temperature-dependence profile demonstrated that copper signals arose a center an environment identical to aa3-type cytochrome-c oxidases reported mammalian, yeast, bacterial systems. purification procedures oxidase was present cytoplasmic membrane at 10 times level thylakoid membrane. be fully redox active by its reducibility with physiological donors.
