Fig. 4-3. Elution profiles of S-proteins from an 

 NADP* specific affinity column. A 2 ' 5' -Sepharose-4B 

 column with a combined NADP* (0-10 uM) and NaCl (0-0.16M) 

 gradient was used as final steps of purification of the 

 S-proteins, each eluting at about O.OlSAf NaCl and luAf 

 NADP. Both SDH (•) and DQT (O) activities coeluted. A) 

 step six of purification of SP-II protein. B) step eight 

 of purification of SP-I protein.
