Figure 4. Effect of Mn²⁺ on the catalysis activity of C. scindens DPEase.

Panel A showed the relative activities in conditions of 0–100 µM Mn²⁺. The curve in the inset represented the effect of Mn²⁺ with broad concentration range from 0 to 600 µM. And panel B represented the linear range of Mn²⁺ concentration effect on the enzyme activity. The experiments were developed with 1 µM C. scindens DPEase.
