WebIn this study we have generated transgenic Arabidopsis plants over-expressing the Rieske FeS protein (PetC), a component of the cytochrome b6f (cyt b6f) complex. Increasing the levels of this protein, resulted in the concomitant increase in the levels of cyt f (PetA) and cyt b6 (PetB), core proteins of the cyt b6f complex. WebThe 2.5 Å structure of the cytochrome (cyt) b 6 f complex provides a basis for control of the rate-limiting electron transfer step of oxygenic photosynthesis associated with the plastoquinol/quinone exchange pathway. Here, a structural change was made at a site containing two proline residues which border the intra-cyt pathway for …
