Glycosylation do occur in some prokaryote, e.g., species of archaebacteria and
eubacteria. However, the types of structures in these species are not found in
other organisms. N-linked oligosaccharides are only found (so far) in eukary-
otes with variations in trimming and modification of the sugar chains.
