Abstract

As discussed by Weber, the presence of the heme severely quenches the emission of the tryptophyl residues in hemoglobin and myoglobin (Weber and Teale, 1959). However, emission signals are still detectable in purified solutions of hemoglobin (Alpert et al., 1980; Hirsch et al., 1981; Hirsch and Nagel, 1981), and their characteristics justify the hypothesis that they are produced by tryptophan.
