The protein structure of cortexillin I (PDB entry 1d7m) contains 19 inter-chain salt bridges that hold the dimer together [only two ion pairs (Asp324 Oδ1 B–Arg325 NH2 A and Glu338 O∊1 B–Lys339 Nz A) are shown for clarity]. (a) Displayed without σs to demonstrate how misleading this is to the unwary reader or user and (b) displayed with σs and an appropriate number of decimal places.
