Fig.2. ¹H-¹⁵N SOFAST-HMQC spectra of α-synuclein under different conditions. (a) The amino acid sequence of α-synuclein, the N-terminus region (1~60) are colored in red; (b) Spectral overlay of α-synuclein in absence (blue) and presence (red) of intact mitochondria, the partial peaks of which signal intensity attenuated in the presence of intact mitochondria are marked; (c) Spectral overlay of α-synuclein with (green) and without (blue) PMSF(1 mmol/L) in diluted solution; (d) Spectral overlay of α-synuclein with (cyan) and without (red) PMSF (1 mmol/L) in the presence of intact mitochondria
