Amphipathic α-helix of A. thaliana HSP 21 and F. hygrometrica HSP 22. The predicted amphipathic α-helices and the corresponding amino acid sequences are shown for the F. hygrometrica and A. thaliana CP sHSPs. The numbers adjacent to the amino acid residues indicate the residue number for the region included in the helical structure. Amino acid residues in large bold text are conserved among all of the angiosperm CP sHSPs. The F. hygrometrica HSP 22 amino acid residues R4 and K1, marked by *, are the only residues that are not identical in HSP 21. However, the replacements in HSP 21 are conservative, with R4 replaced by K and K1 replaced by R.
