Structure of the plant immune signaling node EDS1 (enhanced disease susceptibility 1) in complex with nanobody ENB15

Arabidopsis immunity regulator EDS1 in a PAD4/SAG101-unbound form is a monomer with an inherently inactive conformation.

Structural basis for signaling by exclusive EDS1 heteromeric complexes with SAG101 or PAD4 in plant innate immunity.
