a ATR-FTIR spectra of rMrCP20 and FeCl3 at different molar concentration ratios, illustrating the spectral changes and bond assignments. b Shift in amide I band, indicating a transition of the protein secondary structure transiting towards anti-parallel β-sheets at higher FeCl3 concentrations. c Semi-quantitative secondary structure based on amide I band deconvolution.
