FIG 1 — Composite representation of the heptameric prepore formed by PA₆₃ (Protein Data Bank [PDB] accession no. 1TZO) with EGF (PDB accession no. 1JL9) linked to the C terminus. An axial view of the heptameric prepore is shown, with domains 1, 2, 3, and 4 in a single subunit of PA₆₃ colored magenta, green, gold, and purple, respectively. EGF is in red. Broken lines represent an 8-amino-acid linker (SPGHKTQP) connecting the N terminus of EGF to the C terminus of PA₆₃.
