Figure 1. Diagram of crotoxin A (CA) modeling in the CORAL software⁴³ based on small angle X-ray data.

The amino acid sequences of the three polypeptide chains (α, β and γ) of CA (based on isoform CA₂ sequence), with the residues not modeled in the CA crystal structure highlighted in yellow and the regions modeled as flexible loops in the CORAL software as red boxes. The three N-terminal residues were not modeled because CORAL requires a minimum of five residues to model loops at the N-terminal portion.
