Fig. 3.
NMR temperature spectra for Toolkit peptides. Each stack of 11 spectra show data taken from 8 °C to 58 °C in 5 °C increments. Below each stack is a spectrum taken at 8 °C immediately after the 58 °C spectrum, while the peptide is still non-helical. Single strand Glycine-NH peaks are highlighted in light grey and proton peaks that could be unambiguously assigned and attributed to the helix are highlighted in darker grey.
