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。
