Moreover, superoxide dismutase has the largest kcat/KM (an approximation of catalytic efficiency) of any known enzyme (~7 x 109 M−1s−1), this reaction being limited only by the frequency of collision between itself and superoxide.
Ademais, a superóxido dismutase ten a maior kcat/KM (unha aproximación da eficiencia catalítica) de todos os encimas coñecidos (~7 x 109 M−1s−1), e esta reacción está limitada só pola frecuencia de colisión entre o encima e o superóxido.
