Figure 1
The asymmetric unit of the triclinic crystal form contains two independent copies of the derCD23–Fc∊3-4 complex. Two derCD23 head domains (displayed as Cα traces and surfaces coloured light and dark green) bind to one Fc∊3-4 dimer (coloured light and dark pink). The other two derCD23 domains (coloured light and dark brown) bind to the second Fc∊3-4 dimer (coloured light and dark blue). The carbohydrate is shown in all-atom representation (red and yellow, without surfaces). |
