Figure 6.

The blocks from Figure 3 and Logos from Figure 4, aligned against a BACE1 PDBSum entry. Among the many entries with different ligands the longest sequence was chosen, 3lpi. The 2D display is shaded red to purple for conserved residues but note these are derived from BACE1 alignments (i.e., do not include UrBACEs). The secondary structure elements in dark blue and other marked features are described in the PDBSum features. The red arrows, added from this work, correspond to the six UrBACE sequence blocks.
