International audience; Jacques Breton spent his 39 years of professional life at Saclay, a center of the French Atomic Energy Commission. He studied photosynthesis with various advanced biophysical tools, often developed by himself and his numerous

Characterization of the bonding interactions of QB upon photoreduction via A-branch or B-branch electron transfer in mutant reaction centers from Rhodobacter sphaeroides

Autor: Paul K. Fyfe, Jacques Breton, Marion C. Wakeham, Eliane Nabedryk, Michael R. Jones

In Rhodobacter sphaeroides reaction centers (RCs) containing the mutation Ala M260 to Trp (AM260W), transmembrane electron transfer along the full-length of the A-branch of cofactors is prevented by the loss of the Q(A) ubiquinone, but it is possible

Quinone (QB) Binding Site and Protein Stuctural Changes in Photosynthetic Reaction Center Mutants at Pro-L209 Revealed by Vibrational Spectroscopy

Autor: Jacques Breton, Eliane Nabedryk, Laura Baciou, Pierre Sebban

Publikováno v: Biochemistry. 42:5819-5827

The effect of substituting Pro-L209 with Tyr, Phe, Glu, and Thr in photosynthetic reaction centers (RCs) from Rhodobacter sphaeroides was investigated by monitoring the light-induced FTIR absorption changes associated with the photoreduction of the s

A series of mutations have been introduced at residue 168 of the L-subunit of the reaction centre from Rhodobacter sphaeroides. In the wild-type reaction centre, residue His L168 donates a strong hydrogen bond to the acetyl carbonyl group of one of t

Simultaneous Replacement of Asp-L210 and Asp-M17 with Asn Increases Proton Uptake by Glu-L212 upon First Electron Transfer to QB in Reaction Centers from Rhodobacter sphaeroides

Autor: Mark L. Paddock, Melvin Y. Okamura, Eliane Nabedryk, J. Breton

Publikováno v: Biochemistry. 40:13826-13832

In the photosynthetic reaction center (RC) from Rhodobacter sphaeroides, the first electron transfer to the secondary quinone acceptor Q(B) is coupled to the protonation of Glu-L212, located approximately 5 A from the center of Q(B). Upon the second
