Nod factor as signaling agents binds with the nod factor receptor NFR on the basis for host–symbiont specificity, which of the following is incorrect?

#Unit 6. System Physiology – Plant

NFR is an heterodimer in the cytosolic side that is NFR1 and NFR5
The receptor contains two domain lysin motifs (LysM) in the extracellular domain and kinase domain in the cytosolic side
Receptor contain intracellular domains with similarity to plant serine/threonine protein kinases, but only NFR2 has kinase activity
Lysine of LysM is not consider as amino acid it refer to an enzyme that hydrolyzes bacterial peptidoglycan walls
