In the original version of this article, one major error appears in the figure and two minor errors appear in the figure and the table.

Corrected figure: Fig. 4.

Fig. 4

The NH and αH region of the COSY spectra for melittin in CD₃OH at 25 °C, 35 °C, 45 °C and 55 °C. Intra-residue cross peaks between an NH and an αH are marked with the residue number of the corresponding amino acid

Corrected figure: Fig. 5.

Fig. 5

The Δδ/ΔT’s for melittin in CD₃OH versus the amino acid sequence. The broken line represents the Δδ/ΔT of − 6 ppb/°C. The error bars represent the combined standard uncertainty calculated from the standard error of the linear regression and the propagation of error. The Δδ/ΔT’s for Gly1 and Ile2 are unclear because these NH resonance lines are not observed due to a fast exchange with solvent molecules, and that for Ala4 is unclear due to few experimental data points. The circles denote the relative stability of intra-molecular hydrogen bonds proposed in the published paper (open circle: low stability, gray circle: intermediate stability, closed circle: high stability) [13]

Corrected table: Table 4.
