Sequence alignments of cyanophages, prokaryotes and eukaryotes.

<p>Amino acids comprising β-strands are in gray background. The ACD comprises β2-β9. The CAM L-X-I/L/V of cyanophages and non-classical CAM I/V-X-I/L/V-X-I/L/V of cyanobacteria in the C-terminal extension is in cyan background. Alignment was generated using ClustalW. Secondary structures indicated above are assigned according to the crystal structure of wheat HSP16.9 [21]. GeneBank accession numbers of sequences of cyanophages and cyanobacteria used in this alignment are listed in the Tables 1 and 2, respectively.
