Abstract

Second leaves of broad spectra of wheat cultivars contain three electrophoretically-distinct superoxide dismutases (SODs). One of these resembled the Mn-SOD, becaure it was not inhibited by cyanide ion, but was inactivated with chloroform: ethanol tratment (Tsuchihashi-reagent). The remaining SODs of wheat leaves resembled the Cu, Zn-SODs, which has already been identified from a wide range of eukaryotes. These two Cu, Zn-SODs of wheat leaves were isolated, purified and characterized by amino acid analysis. The amino acid composition of Cu, Zn-SOD was similar from all wheat cultivars, with high Lys content. Results obtained confirm the suggestion that Cu, Zn-SODs production in wheat cultivars is under the control of similar genes. The young leaves of wheat seems to be convenient source of SOD for comparison.
