EPR spectra of 220 μM oxidized TDO, pH 7.4. (A) As-isolated, (B) simulation of (A), (C) with 10 equiv of L-Trp, (D) with 50 equiv of L-Trp, (E) with 110 equiv of L-Trp, and (F) simulation of (E). Experimental conditions: microwaves, 0.2 mW at 9.65 GHz; temperature, 11 K. See text and Table 1 for simulation parameters.
