1 Electron transfer from excited tryptophan to cytochrome c: mechanism of phosphorescence quenching? Tryptophan cytochrome c, somatic Homo sapiens
2 Several lines of evidence support the idea that the reaction of cytochrome c occurred by a long-range electron transfer from the excited triplet state of tryptophan. Tryptophan cytochrome c, somatic Homo sapiens
3 First, cytochrome c quenches the tryptophan phosphorescence and with parvalbumin, its bimolecular quenching rate constant, kq, was 2.9 x 10(6) M-1 s-1. Tryptophan cytochrome c, somatic Homo sapiens
4 Finally, for all illuminated protein samples, the extent of cytochrome c reduction occurred parallel to a decrease in tryptophan content as judged from a decrease in fluorescence intensity and/or a decrease in tryptophan absorption at 280 nm. Tryptophan cytochrome c, somatic Homo sapiens
5 Finally, for all illuminated protein samples, the extent of cytochrome c reduction occurred parallel to a decrease in tryptophan content as judged from a decrease in fluorescence intensity and/or a decrease in tryptophan absorption at 280 nm. Tryptophan cytochrome c, somatic Homo sapiens
