| Interaction of the protein with DPC micelles was confined mainly to the tips of three loops, 4-12, 22-39 and 46-50 (Dubovskii et al. 2001). This is generally consisten with the set of calculated membrane-embedded residues: L6-F10, F25-K36, and S46-V49 (based on locations of NH hydrogens). However, chemical shifts of many residues (primarily Lys and Arg) in the membrane interfacial region have also been affected by the binding. Independent Monte Carlo simulations of the protein led to similar results (Efremov et al. 2002, Dubovskii et al. 2005). |
