3D structures of plant AMPs. a thionin from Crambe hispanica subsp. Abyssinica (PDB:3U7T). b plant defensin from Aesculus hippocastanum (PDB:1BK8). c hevein-like peptide from Gypsophila vaccaria (PDB:5XDI). d knottin-type peptide from Hibiscus sabdariffa (PDB:5GSF). e α-hairpinin family peptide from Nigella sativa (PDB:2NB2). f lipid transfer protein from Hordeum vulgare (PDB:3GSH). g snakin from Solanum tuberosum (PDB:5E5Y). h cyclotide from Clitoria ternatea (PDB:2LAM). The N-terminus and C-terminus of the cyclotide are connected. Red represents the N-terminal amino acid and blue represents the C-terminal amino acid. Green represents the amino-acid skeleton. Yellow represents cysteines and disulfide bridges between cysteines
