Figure 1. The structure of αLP.

The molecule is colored dark blue at the N-terminus progressing to red at the C-terminus. Important structural regions for this work are labeled, including the active site (the catalytic triad of H57, D102, and S195 are represented in ball-and-stick), the N-terminal β-strand (β1, blue), the cis-proline turn (CPT, teal), the Domain Bridge (green), and the C-terminal β-hairpin (CβH, yellow).
