(A) Multiple sequence alignments of the deduced amino acid sequences of GLWamide preprohormones from E. ancora (this study, QAU55050), the stony corals Stylophora pistillata (predicted protein, XP_022779355), Pocillopora damicornis (predicted protein, XP_027060554), and Acropora digitifera (predicted protein, XP_015772272). Identical residues are indicated in gray. The identity threshold was set to 75%. Gaps introduced into the sequences to maximize homology are indicated by hyphens. (B) Comparison of GLWamide preprohormones among different cnidarians. The lengths, repeat numbers of the GLW motif, and sequence identities of the amino acid sequence of EaGLW preprohormone are shown in parentheses. The position of the GLWamide motif is shown as a black box. In addition to the sequences used in the multiple alignment above, sequences from the sea anemones Exapitasia pallida (predicted protein, KXJ28092), Nematostella vectensis (predicted protein, XM_001626406), Anthopleura elegantissima (Q16992), the freshwater Hydra Hydra magnipapillata (XP_002164748), and the marine hydroid Hydractinia echinata (X89734) were used for the comparison.
