[Purification and properties of copper thionein].

A novel procedure for purification of copper-thionein from rabbit liver was developed. The molecular mass, copper, and thiol contents were determined. The properties of the protein were compared with those of Cd-thionein. Copper was removed from Cu-thionein and the reconstitution was achieved. The binding of copper leads to an increase in absorbance at 260 nm.

[Soluble cerebral metalloproteins. II. Superoxide dismutases of cerebral gray and white matter].

Superoxide dismutases (SOD) of high purity have been obtained from grey and white matter of bovine brain cerebral hemispheres. The SOD obtained have been shown to have three isoenzymes (a, b, c). A study of the catalytic and macromolecular properties of the SOD obtained from grey and white matter of cerebral hemispheres as well as their optical and electron paramagnetic resonance spectra indicates that both proteins possess similar properties. The possible function of SOD in grey and white matter of brain is discussed.

[Soluble cerebral metalloproteins. 1. Purification and properties of cerebral cortex cytochrome c].

Cytochrome c from grey matter of brain has been obtained as a homogeneous preparation by electrophoresis on polyacrylamide gel and following electrofocusing in ampholine solutions. Its molecular weight, content of iron, redox potential and isoelectric point have been established. The absolute spectra of its oxidized and reduced forms are presented. Cytochrome c of brain cortex is similar in its properties to that obtained from other animal tissues as the heart and adrenal cortex.
