Abstract After the SOD (superoxide dismutase) was treated with different strength of electric field,the effect of electric field on the secondary structure of SOD was studied by FTIR (Fourier-transformation infrared spectroscopy). The results have shown that different electric field strength has different effects on the secondary structure contents of the SOD. As compared with the contrast,the relative contents of α-helix and β-sheet were decreased,while β-turn content increased. The random coil contents were increased except for the 1.0 kV·cm-1. The electric treatment tends to transform the α-helix and β-sheet into β-turn and random coil,and different strength of electric field has a different effect on the transformation. The changes in SOD activity have a direct relationship to the contents of β-sheet.
