Abstract
Arguments are given for a ferredoxin-mediated reduction of TcO4−, preponderantly into extractable Tc(V) complexes, by illuminated, broken chloroplasts. Photosynthetic O2- and NADP-reduction competitively inhibit Tc incorporation. As for O2, the reaction can be stimulated by the auto-oxidizable electron acceptor methyl viologen. Furthermore TcO4− can function as terminal acceptor in the diaphorase reaction, with NADPH as electron donor.This publication has 14 references indexed in Scilit:
