Fluorescence of Lysozyme: Emissions from Tryptophan Residues 62 and 108 and Energy Migration

Abstract

The bulk of the fluorescence of lysozyme is located in Trp 62 and Trp 108. By examination of the fluorescence of derivatives in which Trp 62 and/or Trp 108 are specifically oxidized, it has been possible to detect a pH-dependent interaction between tryptophan residues. This interaction is interpreted as energy transfer from Trp 108 to Trp 62.

Keywords: pH dependence, spectroscopy, protein structure, enzyme-substrate complex
