| + | == Publication Abstract from PubMed == | ||
| + | Oxytocin is a neuropeptide that binds copper ions in nature. The structure of oxytocin in interaction with Cu(2+) was determined here by NMR, showing which atoms of the peptide are involved in binding. Paramagnetic relaxation enhancement NMR analyses indicated a binding mechanism where the amino terminus was required for binding and subsequently Tyr2, Ile3 and Gln4 bound in that order. The aromatic ring of Tyr2 formed a pi-cation interaction with Cu(2+). Oxytocin copper complex structure revealed by paramagnetic relaxation enhancement NMR analyses. | ||
