Abstract

By the same method as in the previous paper by the author (Bull. Math. Biophysics,23, 55–68, 1961), the mobile electron system is studied in tryptophan which has donated an electron to another molecule. The obtained net charge distribution of tryptophan+ is compared with those of the semiquinones of riboflavin (FMN, FMNH and FMNH 2 + ). From this comparison, a suggestion is obtained for the structure of each of two charge transfer complexes between riboflavin and tryptophan in neutral and acid solution.
