The fluorescence of a folded protein is a mixture of the fluorescence from individual aromatic residues. Most of the intrinsic fluorescence emissions of a folded protein are due to excitation of tryptophan residues, with some emissions due to tyrosine and phenylalanine; but disulfide bonds also have appreciable absorption in this wavelength range. Typically, tryptophan has a wavelength of maximum absorption of 280 nm and an emission peak that is solvatochromic, ran… WebJan 24, 2024 · Tryptophan.

WebFluorescence and phosphorescence measurements have been carried out on single-p tryptophan (Trp 43 or Trp 75)-containing mutants of Tet repressor (Tet R). Tet R containing Trp 43, the residue localized in the DNA recognition helix of the repressor, has been used to observe the binding of Tet R to two 20-bp DNA sequences of tet O1 and tet O2 operators.
