Structures of N. crassa N-linked oligosaccharides as determined by glycan profiling experiments. The N-linked oligosaccharide (left) was isolated from cell wall glycoproteins synthesized by the Δoch-1 mutant, which is unable to elaborate the galactomannan. The full length galacatomannan (middle) was isolated from cell wall glycoproteins synthesized by the Δdfg-5dcw-1 mutant, which lacks the α-1,6-mannanases needed to process the galactomannan. The processed galactomannan (right) was isolated from cell wall glycoproteins synthesized by the Δgel-1gel-2gel-5 mutant, which is unable to incorporate the processed galactomannan into the cell wall.
