Fig. 4. Peptide-binding site of VP22core with the electrostatic potential surface map of the peak side. A peptide consisting of six amino acids was traced from the stretch of unmodelled electron density next to β1. The interaction between the peptide (yellow) and β1 (white) is magnified and displayed below. The peptide fits well into the electron density and the sequence was traced to be SSGSVD. Hydrogen bonds hold the peptide to β1 and these interactions are illustrated by yellow dotted lines.
