WebThe 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. WebDec 2, 2024 · Three of these amino acids — tryptophan, tyrosine, and phenylalanine — have ring structures with fluorescent properties. Of the three, tryptophan exhibits the most …
