Fig. 5 in How is the activity of shikimate dehydrogenase from the root of Petroselinum crispum (parsley) regulated and which side reactions are catalyzed?

Fig. 5. Inhibition effect of various phenylpropanoids on the activity of P. crispum SDH. The specific activity of the enzyme preparations was 0.17 ± 0.07 μmol. min-1mg-1. Controls in 96 and 50 % ethanol were only slightly different from the distilled water control, with specific activities of 0.18 0.06 and 0.19 0.11 μmol. ± ± min-1mg-1, respectively. IC was calculated from nonlinear regression with Eq. (1). Each determination was done at least 3-times, the average values and standard 50 deviations are shown.
