additional information
-
the lack of a plateau prevents the determination of a genuine pH optimum, an apparently linear decrease in activity as a function of pH is not interpretable by standard models of pH-dependent enzyme activity which predict sigmoidal or bell-shaped profiles
8.5
-
the osmium-wired sulfite oxidase shows the same optimum pH (8.5) as in solution with cytochrome c
