title: [Isolation and properties of superoxide dismutase from human blood plasma].
abstract: A procedure for purification of superoxide dismutase (SOD) from human blood plasma has been developed, which includes gel filtration on Ultrogels AcA-34 and AcA-44 (LKB, Sweden). The protein purified from blood plasma is a glycoprotein which is thermostable at 70-80 degrees C. The molecular mass of the protein determined immediately after gel filtration is approximately 147,000 daltons. A comparative analysis of effects on the SOD activity of plasma and erythrocytes of compounds capable of forming chelating complexes with metals within the enzyme active center has been carried out. The purified enzyme differs by its physico-chemical characteristics from cytosolic Cu,Zn-SOD and pertains to a new class of SOD, the so-called extracellular SOD, detected in some biological fluids.
