Fig. 5-10. Saturation curves and double reciprocal 

 plots for SP-I. A) Saturation of shikimate dehydrogenase 

 when substrate, NADP*, was held constant at 0.5 mM and 

 substrate, shikimate, was varied over a range of 0.25 mM 

 to 5 mM. B) A double reciprocal plot of the data obtain- 

 ed in A when SHK was the variable. C) Saturation of SDH 

 when SHK was held constant at 5 mM and NADP* was varied 

 over a range of 0.01 mM to . 5 mM. D) A double recipro- 

 cal plot of the data obtained from B when NADP* was the 

 variable .
