In order to research the effects of minimum tillage and no-tillage patterns on yield and senescence of flag leaf of winter wheat, four tillage patterns were adopted in Longkou city, Shandong Province, China for three years. Four tillage patterns were as follows: conventional tillage with straw turnover, rotary tillage with straw turnover, serrated disk harrow tillage with straw turnover, no-tillage with straw cover. Effects of different tillage patterns on the activities of superoxide dismutase, peroxidase and the contents of malondialdehyde and soluble protein of the winter wheat flag leaves after anthesis were analyzed.

Since the dismutation of superoxide radicals by SOD is a reaction that is rate-limited by diffusion and enhanced by electrostatic guidance, all these structural features may be related to GP-MnSOD's high catalytic activity: first, Lys38 may increase the effective enzyme-substrate association rate by enhancing the electrostatic gradient at its substrate channel; second, an excess of acidic over basic residues makes the negative surface potential of GP-MnSOD more larger than those of other known MnSODs. This may enhance the reaction rate by reducing futile collisions of superoxide radicals with GP-MnSOD's surface.
因此,GP-MnSOD的上述结构特征可能与GP-MnSOD的较高酶活有关:首先,Lys38增加了底物通道口的正静电势梯度,从而可能促进了GP-MnSOD的活性中心与底物的有效结合速率;其次,GP-MnSOD表面覆盖的过量酸性残基使得它比其它MnSOD在底物通道以外的蛋白表面更多地被负静电势所覆盖,这可能有效地减少了超氧阴离子与GP-MnSOD表面的无效碰撞,从而提高了反应速率。
