ePHOGSY signal intensities for NOE
. The normalized intensities of the observed ePHOGSY proton signals are shown as filled bars. The presence (filled circle) or the absence (open circle) of a vicinal MDHS (computed for a distance of 0.35 nm from each hydrogen) is shown. For amino acids not exhibiting an ePHOGSY signal (absence of intensity bars), the presence of MDHS was taken as positive if at least one of the hydrogens was within the 0.35 nm cut-off distance.
