Alignment of F. hygrometrica and angiosperm CP sHSPs. The alignment contains F. hygrometrica CP sHSPs, HSP 22, and HSP 21; monocot, Triticum aestivum (T.a.), Zea mays (Z.m.) and dicot A. thaliana (A.t.), Pisum sativum (P.s.) CP sHSPs, as well as HSP 16.6 from Synechocystis sp. The transit sequence consists of positions 1–51. The N-terminal domain consists of residues 52–146, and the C-terminal domain starts at residue 147. Gaps in the alignment are noted by a ⋅. The glutamine (Q) residue that is predicted to mark the start of the mature CP sHSPs is in bold italics. The methionine (M) residues conserved among angiosperm CP sHSPs are noted with *. Residues that are conserved among all sHSPs (eukaryotic, bacterial, and archaeal) are noted with #. A lack of a consensus residue is noted by –. Three consensus sequences are presented. The first is the angiosperm CP sHSPs consensus. The second is the land-plant CP sHSPs (including the F. hygrometrica sHSPs) consensus sequence. The third consensus sequence is based on all of the sequences, including Synechocystis HSP 16.6. The previously identified conserved consensus regions I, II, and III, discussed in the text, are in bold.
