Figure 5.

The fingerprint region of TOCSY experiments of HKP1 in the presence of (A) dDPC, and dDPC with (B) 5-doxyl stearic acid, or (C) 12-doxyl stearic acid. Signals in close proximity to the nitroxide spin labels, which partition into the micelle, will shift or disappear. The remaining signals are distant from the spin labels, and in most cases, in contact with the aqueous environment. To the right of the spectra are idealized helical wheels of the apoptotic sequences. Amino acids with gray circles are not present in the spectrum.
