13C Magic angle spinning NMR characterization of the functionally asymmetric QA binding in Rhodobacter sphaeroides R26 photosynthetic reaction centers using site-specific 13C-labeled ubiquinone-10

Autor: Peter Gast, G.J. Boender, W.B.S. van Liemt, H. J. M. de Groot, Johan Lugtenburg, A. J. Hoff

Publikováno v: Biochemistry, 34(32), 10229-10236

Photosynthetic reaction centers (RCs) of Rhodobacter sphaeroides R26 were reconstituted at the Q{sub A} site with ubiquinone-10, selectively {sup 13}C-enriched on positions 1, 2, 3, 4, and 3-Me (IUPAC numbering). RCs dispersed in LDAO detergent were

13C MAS NMR evidence for a homogeneously ordered environment of tyrosine M210 in reaction centres of Rhodobacter sphaeroides

Autor: S. H. Van Leeuwen, Johan Lugtenburg, G.J. Boender, Arnold J. Hoff, W.B.S. van Liemt, Erik Vijgenboom, Jan Raap, Peter Gast, Susana Shochat, H. J. M. de Groot

Publikováno v: Spectrochimica Acta Part A : Molecular and Biomolecular Spectroscopy, 51(1), 135-144

The initial electron transfer time in the photosynthetic reaction centre of Rhodobacter sphaeroides is highly sensitive to the replacement of tyrosine M210 by a tryptophan residue. Low-temperature magic angle spinning 13 C NMR is used to study Rhodob
