متن کاملOn the Ligand Field of Iron in Ferredoxin from Spinach Chwroplasts and Related Nonheme Iron
The suspected structural relationship between the ferredoxin group of enzymes, recently found to participate in a variety of biological electron transfer reactions, 1 and other nonheme iron enzymes has acquired substantial support by our recent finding2 that the ferredoxin isolated from spinach chloroplasts exhibits under reducing conditions an EPR spectrum of the type now well known for other ...
متن کاملInteractions between spinach ferredoxin-nitrite reductase and its substrates. Evidence for the specificity of ferredoxin.
Reduced ferredoxin can serve as electron donor in the 6-electron reduction of nitrite to ammonia catalyzed by spinach nitrite reductase. We have examined interactions between nitrite reductase and its substrates, ferredoxin and nitrite, with emphasis upon protein-protein interactions between ferredoxin and nitrite reductase. Ferredoxin, of the proteins tested, is the most effective in retarding...

to detect hybrid particles. Although the RNA of dependent virus often replicated to a level about 10 per cent of that of supporting virus,' maturation of intact dependent virus within heterologous capsid was much less efficient. This could be due to a better fit between capsomeres and homologous RNA or it could be due to a spatial relationship between capsomere protein synthesis and the viral R...
متن کاملMetabolic Interactions between Spinach Leaf Nitrite Reductase and Ferredoxin-NADP Reductase: Competition for Reduced Ferredoxin.
Steady state rates of NADP reduction decline upon commencement of nitrite reduction in reconstituted chloroplast preparations. Similarly, steady state rates of nitrite reduction are lower, but not zero, during concurrent NADP reduction. These results imply that competition for substrate occurs and suggest that nitrite reduction can successfully compete for reduced ferredoxin, even at high rates...
