Crystal structures of bovine knob domains Panel (a) shows a bovine Fab with an ultralong CDRH32. The CDRH3 is shown in isolation in panel (b) with networks of disulfide bonds highlighted. Panels (c and d) show the K92 and K8 knob domains, respectively,4 where the N- and C- termini remain in close proximity.
The figure shows the crystal structure of a bovine Fab with an ultralong CDRH3, the disulfide-rich knob domains are highlighted.
