Tryptophan 136-139 cryptochrome Drosophila melanogaster 63-69 25710635-4 2015 Calculated excitation energies, followed by electron transfer in model compounds of DmCry1 that assume proton transfer in conjunction with electron transfer from Trp (W420) to FAD and the predicted pKa for the proximate residue to FAD (Cys416), support a radical-pair mechanism. Tryptophan 162-165 cryptochrome Drosophila melanogaster 84-90 25710635-5 2015 Furthermore, free-energy and reorganization energies for the Trp-triad in DmCry1 demonstrate facile electron transfer, explained by the local protein environment and exposure to solvent, which in turn enables a large enough distance separation for the radical-pair partners. Tryptophan 61-64 cryptochrome Drosophila melanogaster 74-80 11818067-6 2002 Two tryptophan residues in dCRY are critical for its function and are likely involved in an intramolecular redox reaction.
