Spectroscopic comparison of photogenerated tryptophan radicals in azurin: effects of local environment and structure.

Journal of the American Chemical Society - 7 Jul 2010

Abstract excerpt

Tryptophan radicals play a significant role in mediating biological electron transfer. We report the photogeneration of a long-lived, neutral tryptophan radical (Az48W*) from the native residue tryptophan-48 in the hydrophobic core of azurin. The optical absorption, electron paramagnetic resonance, and resonance Raman spectra strongly support the formation of a neutral radical, and the data are consistent with...
