Figure 4

Cartoon representation of the AS8 crystal structure. a. The elements of AS8 secondary structure are labeled. Structural elements that are unique to AS8 are colored in orange (helix Aα1), red (helix Aα2) and yellow (AL1, AL2, and AL3). The strands of the N-terminal β-sheet (β1, β2, β3) are colored in purple, cyan, and blue respectively. b. Tertiary structure connecting the subdomain formed by the AS8 insertion peptide and N-terminal domain. Only the N-terminal domain is shown. The side-chains are colored according to their corresponding secondary structure element. Residues Pro28 and Tyr57 are not visible in this orientation.
