Spectral studies on the state of tryptophan residues in the e fragment of fibrinogen

The state of tryptophan residues in the E-fragment of fibrinogen is studied by the methods of thermal-perturbation difference spectrophotometry and quenching of fluorescence. In the thermal-perturbation difference spectrum of the E-fragment, the maximum is observed in a 305 nm region. It evidences for the presence of tryptophan residues inaccessible to the solved and situated in hydrophobic regions. After the E-fragment denaturation with the 8 M guanidine HCl, the 305 nm maximum disappears.
