A Ru-II-TAP Complex, Photoreagent for Tryptophan-Containing Peptides: Structure of the Covalent Photoadduct
We report the first structure determination of a covalent photoadduct between a Ru-II-tap complex and a tryptophan-containing peptide (AlaTrpAla) by mass spectrometry and NMR spectroscopy. Ru-II-tap complexes could thus be exploited as photodamaging agents of Trp-containing polypeptides or proteins.
