Representative sea anemone toxins with BBH mortif. (A) Alignment of representative sea anemone toxins that adopt the BBH motif. Disulfide connectivities are indicated above the sequence alignment. Amino acid identities (black boxes) and similarities (grey boxes) are highlighted. The representative toxin sequences shown are SHTX-1 (κ-stichotoxin-Shd1a; UniProt P0C7W7), Bcg-III-23.41 (U-BcgTx1a; UniProt P86467), U-SHTX-Sdd1 (UniProt C0HJB4), Ugr9-1 (π-AnmTX Ugr 9a-1; UniProt R4ZCU1), Am-1 (Δ-AITX-Amc1a; UniProt P69929), Ms9a-1 (T-AnmTX Ms 9a-1; UniProt C0HK13), Ms9a-2 (T-AnmTX Ms 9a-2; UniProt C0HK13) and Ms9a-3 (T-AnmTX Ms 9a-3; UniProt C0HK13). (B) 3D structure of the sea anemone toxin Ugr9-1 (PDB 2LZO). The two disulfide bonds are represented by orange tubes.
