Peptide Synthesis> | 5% Tween-20) for 1–2 hours, followed by immunoblotting with the primary antibody specified for each experiment: antibodies against N-terminal residues of cytochrome b6 as well as against the interhelical part of cytochrome b6 (between helix 1 and 2 and between helix 3 and 4)19, and against ALB336 were prepared in rab- bits injected with the synthetic peptide (GenScript); biotin antibody was purchased from Abcam® (ab53468). | Get A Quote |
The cytochrome b f complex occupies an electrochemically central position in the electron-transport chain bridging the photosynthetic reaction center of PS I and PS II. In plants, the subunits of these thylakoid membrane protein complexes are both chloroplast and nuclear encoded. How the chloroplast-encoded subunits of multi-spanning cytochrome b are targeted and inserted into the thylakoid membrane is not fully understood. Experimental approaches to evaluate the cytochrome b import mechanism in vivo have been limited to bacterial membranes and were not a part of the chloroplast environment. To evaluate the mechanism governing cytochrome b integration in vivo, we performed a comparative analysis of both n... More
