Fig. 3

Effect of pH on the activity of purified Lcc120-3 (Mic-mg-MCO) for ABTS and DMP. Closed circles indicate acetate buffer (pH 4.0–6.0), open circles indicate citrate-NaOH buffer (pH 5.5–7.0), closed squares indicate KPB (pH 6.5–8.0), and open squares indicate Tris–HCl buffer (pH 7.5–9.0). The dotted line indicates the activity for ABTS, and the solid line indicates the activity for DMP. Relative activity is shown as 100% at each optimal pH
