6-aminohexanoic acid (cas 1319-82-0)-plasminogen interactions studied by fluorescence

Add time:08/22/2019    Source:sciencedirect.com

Circular polarization of luminescence spectra of human plasminogen and of its derivatives were measured in solutions of ligand-free proteins and with saturating amounts of 6-aminohexanoic acid. Spectroscopic changes induced by the ligand reveal similar perturbations of the binding sites in all the protein derivatives. It is concluded that the gross conformational change induced by 6-aminohexanoic acid binding to the native plasminogen involves changes of sterical relations of entire protein domains.
