EPR spectra obtained at the X-band for the outward-facing spin-labeled BtuB mutant T156R1 in (A) DMPC and (B) POPC at three different temperatures (17°C, 23°C, and 28°C) extending below and above the gel-liquid crystalline phase transition of DMPC (23°C). (B) Arrows indicate positions of hyperfine extrema (2Azz′) for an immobilized component in the POPC spectrum of T156R1. T, temperature.
