Figure 6.
EPR spectra of BtuB T156R1 reconstituted into POPC vesicles, and spectra from 11 mutants of T156R1, reconstituted into POPC bilayers, where the nearest neighboring residues have been mutated. These spectra include those from mutations to the i±2 residues (V154, Q158), the hydrogen-bonded (L168) and non-hydrogen bonded (T138) neighbors, and residue L160, which is on a periplasmic turn and forms the apex of a hydrophobic pocket near 156R1. The dashed lines below each spectrum represent the MOMD simiulations for each spectrum (see Table 3 for the parameters used to generate each spectrum). All spectra are 100 Gauss scans.
