Table 4 in How is the activity of shikimate dehydrogenase from the root of Petroselinum crispum (parsley) regulated and which side reactions are catalyzed?

Table 4 The effect of various ions on P. crispum SDH activity. Screening was performed spectrophotometrically at 340 nm in the presence of 3 mM SA, 0.2 mM NADP and 5 mM*, 0.1 mM**, or 0.01 mM*** concentration of potential modulator. Each determination was done at least 3-times, the average values and S.D. are shown.
