Hyperfine and Nuclear Quadrupole Tensors of Nitrogen Donors in the Q(A) Site of Bacterial Reaction Centers: Correlation of the Histidine N(δ) Tensors with Hydrogen Bond Strength
[Image: see text] X- and Q-band pulsed EPR spectroscopy was applied to study the interaction of the Q(A) site semiquinone (SQ(A)) with nitrogens from the local protein environment in natural abundance (14)N and in (15)N uniformly labeled photosynthetic reaction centers of Rhodobacter sphaeroides.
