Fig. 5-7. Temperature optima for S-proteins. 

 Optimal activity was determined for both SP-I and SP-II 

 purified proteins over a range of temperatures from 24°C 

 to 66°C. A) Dehydroquinate dehydratase activity was 

 determined for the temperature range given. B) Shikimate 

 dehydrogenase activity was determined over the given 

 temperature range .
