Figure 1. Pharmacophores of α-dendrotoxin and BPTI (in red
sticks). Residues implicated in the binding of α-dendrotoxin (PDB: 1dtx)
with Kv1.1 (Gasparini et al., 1998, A ), and BPTI (P13A variant,
PDB: 1qlq) with serine proteases (Otlewski et al., 2001, B ).
Loops are colored in green (loop 1) and magenta (loop 2).
