Correlations between log(kcat/Km) and ΔE0 for phenothiazines and phenoxazines. Symbols: ○, oxidation by TvL of 3 phenoxazines and 20 phenothiazines (see Materials and Methods for their formulas) (20a); ▵, oxidation of PP (E0, 0.71 V) by TvL, RsL, MtL, StL, and MvBO at pH 5.3 to 5.5. Correlation: log(kcat/Km) = 5.1(▵E0) + 6.4 (r2, 0.47). Units: kcat/Km, M−1 min−1; ΔE0, V.
