Dependence of (kcat/Km)obs for ScTIM-catalyzed turnover of the free carbonyl form of [1-13C]-GA in D2O on the concentration of added dianion for reactions at pD 7.0, 25 °C and I = 0.1, NaCl. The solid lines show the fits of the data to eq 3 derived for Scheme 2: (A) ●, HPO32–;▼, FPO32–. (B) ●, S2O32–; ▲, SO42–; ■, HOPO32–.
