Dependence of the initial reaction rate on the mixing ratio of substrates and t -butyl alcohol. The initial rate without t-butyl alcohol (control) was 9.68 nmol h^-1 U^-1), and its relative rate was regarded as 1.0. Symbols white diamond, △, □, ○, black diamond, black triangle, and black square represent the relative initial rate in the ranges of 0.30–0.99, 1.0–1.9, 2.0–2.9, 3.0–5.0, 7.0–7.9, 8.0–8.9, and 10–11, respectively. The symbol inside the dotted circle represents the control. The reaction condition was the same as that in Fig. 1 except for the mixing ratio.
