Photo-chemically induced dynamic nuclear polarization (photo-CIDNP) one-dimensional and two-dimensional (2D) 1H-NMR techniques have been applied to the study of the kringle 4 domain of human plasminogen both ligand-free and complexed to the antifibrinolytic drugs epsilon-aminocaproic acid and p-benzylaminesulfonic acid (BASA). A number of aromatic side-chains (His3, Trp72, Tyr41, Tyr50 and Tyr74) appear to be exposed and accessible to 3-N-carboxymethyl-lumiflavin, the photopolarizing flavin dye, both in the presence and in the absence of ligands. A lesser exposure is observed for the Trp25 and Trp62 indole groups in the presence of BASA. The spin-spin (J-coupling) and dipolar (Overhauser) connectivities in the 2D experiments afford absolute assignment of aromatic resonances for the above residues, as well as of those stemming from the Trp72 ring in the presence of BASA. Moreover, a number of H beta resonances can be identified and sorted according to specific types of amino acid residues.
