Identification and characterization of novel cecropins from the Oxysternon conspicillatum neotropic dung beetle
Fig 2
Oxysterlin mature peptide structures.
Structures of oxysterlins 1 to 3 had predicted α-helix structure; with an amino terminal region with an amphipathic region corresponding to the oxysterlin domain with a 120° hydrophobic angle and a more hydrophobic carboxyl terminal region. Oxysterlin 4 has an α-helix amino-terminal domain and a β-sheet carboxyl terminal structure. All the structures show an amphipathic amino terminal and a hydrophobic carboxyl-terminal domain (red: hydrophobic, white: neutral, and blue: hydrophilic).
