Purified antisera against ferredoxin, ferredoxin-NADP+ reductase and plastocyanin agglutinated osmotically shocked and washed spinach chloroplasts, prepared according to standard procedures. The monomeric antibody (immunoglobulin G fraction) of the reductase antiserum agglutinated chloroplasts specifically and directly, indicating that protruding structures (for example, the coupling factor) do not act as steric hindrances as has been suggested. With ferredoxin antiserum, the presence of a pentameric antibody (immunoglobulin M fraction) was obligatory to observe a positive agglutination reaction. Immunoglobulin G only inhibited ferredoxin-dependent reactions, like NADP+-photoreduction, but did not cause agglutination. Ferredoxin seems to be located in depressions of the membrane, possibly caused by a partial release of this protein in shocked chloroplasts. Similar results were obtained with purified immunoglobulins from a plastocyanin antiserum. Again the immunoglobulin G fraction inhibited electron transport reactions catalyzed by plastocyanin, whereas immunoglobulin M showed a positive agglutination, but had no influence on electron transport. It is concluded that ferredoxin, ferredoxin-NADP+ reductase and plastocyanin are peripheral electron transport components, located at the outer thylakoid membrane.
