A: Lti30 amino acid sequence with the hydrophobic parts making up the unstructured part of the bound protein marked in orange and the hydrophilic K-segments marked in blue. The histidine amino acids flanking the K-segments are marked in red. B: Schematic representation of the whole Lti30 protein with the K-segments marked as blue squares. The part of the K-segment that folds into an α-helix upon binding with the lipid membrane is marked in green. C: Sketch of the lamellar liquid crystalline, reversed hexagonal, and bicontinuous cubic phase, respectively.
