Crystallographic confirmation of DEL-II sequence. The four amino acid positions at which Pekin DEL isoforms differ (columns on the left) are compared with composite omit map electron density for the DEL-II structure (RHS, contoured at 1 standard deviation above the mean). Sticks coloured grey belong to symmetry related molecules within the crystal lattice. Sequences corresponding to the DEL-II isoform are coloured blue. At position 100, multiple conformers of Ser100 were refined (adjacent multiple conformers of Arg114 within a neighboring molecule)
