Abstract excerpt
Time-resolved fluorescence experiments were carried out on a variety of apomyoglobins with one or two tryptophan (Trp) residues located at invariant positions 7 and 14 in the primary sequence. In all cases, the Trp fluorescence kinetics were resolved adequately into two discrete lifetime domains, and decay-associated spectra (DAS) were obtained for each decay component. The DAS resolved for unfolded proteins were...
