High efficient cyclic electron flow and functional supercomplexes in Chlamydomonas cells

Autor: Pierre, Joliot, Julien, Sellés, Françis-André, Wollman, André, Verméglio

A very high rate for cyclic electron flow (CEF) around PSI (~180 ssup-/sup1 or 210 ssup-1/supin minimum medium or in the presence of a carbon source respectively) is measured in the presence of methyl viologen (MV) in intact cells of Chlamydomonas re

The chloroplast ATP synthase (CF1Fo) contains a specific feature to the green lineage: a γ-subunit redox domain that contains a cysteine couple which interacts with the torque-transmitting βDELSEED-loop. This thiol modulation equips CF1Fo with an i

ECS-based investigation of chloroplast ATP synthase regulation

Autor: Pierre Joliot, Felix Buchert, Benjamin Bailleul

The chloroplast ATP synthase (CF1Fo) contains a specific feature to the green lineage: a γ-subunit redox domain which contains a cysteine couple and interacts with the torque-generating βDELSEED-loop. Based on the recently solved structure of this

In vivo electron donation from plastocyanin and cytochrome c to PSI in Synechocystis sp. PCC6803

Many cyanobacteria species can use both plastocyanin and cytochrome c6 as lumenal electron carriers to shuttle electrons from the cytochrome b6f to either photosystem I or the respiratory cytochrome c oxidase. In Synechocystis sp. PCC6803 placed in d

International audience; Cyclic electron flow (CEF) is defined as a return of the reductants from the acceptor side of Photosystem I (PSI) to the pool of its donors via the cytochrome b6f. It is described to be complementary to the linear electron flo
