Comparison of Cu(II)-binding induced tryptophan fluorescence quenching of synthetic peptides and full length α-syn variants. Tryptophan fluorescence quenching was not observed when the α-amino termini of the peptides were acetylated ([peptide/protein] = 1.0 ± 0.2 μM in deoxygenated 20 mM MOPS, 100mM NaCl, pH 7.0 buffer). All C-termini in the peptides are amidated (denoted as −NH2).
