Fine tuning the structure of the Cu2+ complex with the prion protein chicken repeat by proline isomerization.
The interaction between the single hexarepeat unit of chicken prion protein [ChPrP(54-59)] and Cu(II) was investigated by NMR, finding different coordination modes for the trans/trans and cis/trans isomers.
