An ultra-high affinity protein–protein interface displaying sequence-robustness
Protein–protein interactions are crucial in biology and play roles in for example, the immune system, signaling pathways, and enzyme regulation. Ultra-high affinity interactions (Kd <0.1 nM) occur in these systems, however, structures and energetics behind stability of ultra-high affinity protein–protein complexes are not well understood.
