(A) Fluorescence spectra (λex = 325 nm) and (B) fluorescence decay kinetics (λex = 270 nm) of 4CN-Trp*-Gly and 4CN-Trp*-Met, as indicated. The optical densities of both samples at λex were equal. Fitting each fluorescence decay in B to a single-exponential function (black) yielded a lifetime of 12.6 ns for 4CN-Trp*-Gly, and 12.2 ns for 4CN-Trp*-Met. The residuals to the fits are shown at Top.
