The nature of CuA in cytochrome c oxidase

The isolation and purification of yeast cytochrome c oxidase is described. Characterization of the purified protein indicates that it is spectroscopically identical with cytochrome c oxidase isolated from beef heart. Preparations of isotopically substituted yeast cytochrome c oxidase are obtained incorporating [1,3-15N2]histidine or [beta,beta- 2H2]cysteine. Electron paramagnetic resonance and electron nuclear double resonance spectra of the isotopically substituted proteins identify unambiguously at least 1 cysteine and 1 histidine as ligands to CuA and suggest that substantial spin density is delocalized onto a cysteine sulfur in the oxidized protein to render the site Cu(I)-S

Closing the gaps in quantum space and time : Conformally augmented gauge structure of gravitation

C. W. wishes to thank C. J. Isham and J. W. York for encouragement in pursuing the conformal properties of (loop) quantum gravity. The referee’s constructive criticism has been very helpful in clarifying the presentation of results and their context. For financial support, C. W. and D.
