Figure 7.

Alignment of polypeptide structures retrieved with motif 4 vs. BPTI/Kunitz family of serine proteinase inhibitors and toxins (P10280, Q9TWG0, Q9TWF9, Q9TWF8). Mature polypeptides are shown in black, while signal peptides and propeptide domains are given in light brown; amino acids that differ from the kalicludine-1 sequence are shown in red.
