Fig. 4. Sequences and theoretical 3D model of rCeEIbased peptides. (A) Alignment of amino acid sequences of rCeEI-36, rCeEI-46 and rCeEI-55. The cysteine residues are in black box, and residues at P1 and P1′ positions of the putative reactive site are highlighted in green. The peptides (B) rCeEI-36 and (C) rCeEI-46 are in green and red, respectively. The putative reactive site is in cyan and the disulfide bond in rCeEI-36 is shown in yellow.
