Figure 5. Schematic of the polyamine-binding site in Tp0655,
PotD, PotF with spermidine as a reference. Listed are all
residues that interact with ligand in PotD and PotF as well as
structurally equivalent (based on C^α positions) residues in
the other proteins. Residues in lower-case letters are
structurally equivalent but their side-chains do not establish
interactions with the ligand.
