Multiple alignment of amino acid sequences from 17 prokaryotic cellulose synthase homologs with CesA sequences from Arabidopsis, Gossypium hirsutum, corn, Populus tremulus × Populus alba, and D. discoideum. The alignment demonstrates the presence of a CR-P region between the U1 and U2 domains present only in eukaryotic and cyanobacterial sequences.
