RT Journal Article T1 The folding of a metallopeptide A1 Gamba, Ilaria A1 Rama, Gustavo A1 Ortega-Carrasco, Elisabeth A1 Berardozzi, Roberto A1 Sánchez Pedregal, Víctor Manuel A1 Di Bari, Lorenzo A1 Maréchal, Jean-Didier A1 Vázquez Sentís, Marco Eugenio A1 Vázquez López, Miguel AB We have applied solid-phase synthesis methods for the construction of tris(bipyridyl) peptidic ligands that coordinate Fe(II) ions with high affinity and fold into stable mononuclear metallopeptides. The main factors influencing the folding pathway and chiral control of the peptidic ligands around the metal ions have been studied both by experimental techniques (CD, UV-vis and NMR) and molecular modeling tools. Amongst the numerous molecular variables that have been studied, this study clearly illustrates how the chirality of a given set of aminoacids (proline in this case) of the peptide dictates the chirality of the metal center of the resulting metallopeptide. Moreover, the relatively hydrophobic peptidic models used in this work show that the most stable structures present reduced solvent contacts and, in counterpart, stabilize the cis configuration of the proline residues PB Royal Society of Chemistry SN 1477-9226 YR 2016 FD 2016 LK http://hdl.handle.net/10347/17022 UL http://hdl.handle.net/10347/17022 LA eng NO Gamba, I., Rama, G., Ortega-Carrasco, E., Berardozzi, R., Sánchez-Pedregal, V., & Di Bari, L. et al.
