✦ Synopsis

revealed that 90% of the erythrocyte copper is bound in superoxide dismutase. Only 10% of the copper is found in the high molecular fraction following gel filtration of the haemolysate. All other copper proteins migrate in the region near M, = 32 000.

The yield of both superoxide dismutase and Cuz-(haem,,),-protein clearly shows that the copper of the red blood cell is distributed in these proteins. Taking into account minimal losses of intracellular copper in the course of the fractionation steps no copper proteins other than the preceding ones were detectable. It appears that CuzZnz superoxide dismutase or cuprein is the major intracellular copper protein.
