Scheme of the linker segment. Schematic representation of the amino acid sequence corresponding to the linker segment (aa 390–500) of the sequence of the ACT toxin (Acc ni 6092563 emb CAB59146.1, which includes a prediction of the most probable secondary structure elements that was determined with the I-Tasser predictor [50]. The peptide segment extending between residues 454 and 485 (P_454–485) has been indicated with a double-head arrow. In red appear mutated arginines, and in green, mutated aspartic and glutamic acids [51].
