Axial coordination of heme in ferric CcmE chaperone characterized by EPR spectroscopy.

Biophysical journal - 15 Feb 2007

García-Rubio Inés, Braun Martin, Gromov Igor, Thöny-Meyer Linda, Schweiger Arthur

Abstract excerpt

In Escherichia coli cytochrome c maturation requires a set of eight proteins including the heme chaperone CcmE, which binds heme transiently, yet covalently. Several variants of CcmE were purified and analyzed by continuous-wave electron paramagnetic resonance, electron nuclear double resonance, and hyperfine sublevel correlation spectroscopy to investigate the heme axial coordination. Results reveal the presence...
