There are three essential nod gene for every bacterial species that is−NodA, NodB and NodC, that are required for synthesizing this basic structure such as;
a) NodA is an N-acyltransferase that catalyzes the addition of a fatty acyl chain
b) NodB is a chitin-oligosaccharide synthase that links the acetyl group of the terminal nonreducing sugar
c) NodC is a chitin-oligosaccharide synthase that links N-acetyl-D-glucosamine monomers
d) NodB is a chitin-oligosaccharide deacetylase that removes the acetyl group from the terminal nonreducing sugar
e) NodC is a chitin-oligosaccharide deacetylase that removes links N-acetyl-D-glucosamine monomers
