Four novel oligosaccharide units were isolated from the acetolysis products of the acidic polysaccharide chain derived from the glycoproteins of Fusarium sp. M7-1. Their chemical structures were resolved mainly by 1H-NMR spectrometry in combination with methylation analysis and mass spectrometry. The results indicate that these oligosaccharide units originated from the side chains, GlcNAccl→4GlcAal→2(GlcNAcαl→4)GlcAαl→2Gal, GlcNAcαl→4GlcAαl→2(GlcNAcαl→4)GlcAαl→2(GlcNAcαl→4)GlcAαl→2Gal, ChN←-P→ 6Manβ1→4GlcAαl→2Gal, and Manβ1→2(ChN←P→6)Manβl→4GlcAαl→2Gal linked together with the other units reported previously [Jikibara et al. (1992) J. Biochem. 111, 236-243] through βl→6galactofuranoside linkages in the acidic polysaccharide chain.
