Hexapeptides incorporating two fluorophores flanking a tripeptide sequ
ence that binds Ni(II) and Cu(II) with high affinity have been synthes
ized. While Cu(II) quenches the fluorescence of the resulting peptides
, coordination of Ni(II) enables enhanced FRET (fluorescent resonance
energy transfer) from one fluorophore to the other. (C) 1998 Elsevier
