1.8.2.1 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 743146 1.8.2.1 6.5 - - 394084 1.8.2.1 7.5 - - 394083, 394088 1.8.2.1 7.8 - reaction with native cytochrome c 394078 1.8.2.1 8 - - 394072, 394087 1.8.2.1 8 - about pH 8.0 710857 1.8.2.1 8 - assay at 743146 1.8.2.1 8 - potassium phosphate buffer 394077 1.8.2.1 8 - with Tricine-HCl or Tricine-NaOH buffer 394081 1.8.2.1 8.5 - - 394079, 724587
