  Synthesis and Spectroscopic Characterization of [5-13C]- and [6-13C]Ubiquinone-10 for Studies of Bacterial Photosynthetic Reaction Centers

  摘要：

  This paper presents the synthesis and characterization by mass spectrometry and NMR spectroscopy of [2-C-13]- and [3-C-13]ubiquinone-0 and of [5-C-13]- and [6-C-13]ubiquinone-10. A scheme based on the synthetic approach to [5-C-13]ubiquinone-10 has been worked out for the synthesis of ubiquinones C-13-labeled at any individual position and at every combination of positions in the quinone ring. The [5-C-13]- and [6-C-13]ubiquinone-10 isotopomers were incorporated into the Q(A)-site of the photosynthetic reaction center of Rhodobacter sphaeroides R-26. Magic angle spinning NMR subsequently revealed an unperturbed 6-position, while the signal of the 5-position was absent. These results corroborate the recently reported detection of an asymmetric binding of Q(A) with a dynamic perturbation involving the 4-carbonyl functionality.
