NodA is an N-acyltransferase that catalyzes the addition of a fatty acyl chain.

NodB is a chitin-oligosaccharide deacetylase that removes the acetyl group from the terminal nonreducing sugar.

NodC is a chitin-oligosaccharide synthase that links N-acetyl-D-glucosamine monomers.

The binding of Nod factors to the Nod factor receptors (NFRs), which contain extracellular LysM motifs, initiates an interaction with the conserved SYMRK receptor-like kinases containing a leucine-rich repeat (LRR) domain.
