O-glycosidically linked oligosaccharides from peptidorhamnomannans of Sporothrix schenckii.
beta-Elimination of peptidorhamnomannans purified from yeast-like and mycelial phases of Sporothrix schenckii released neutral and acidic reduced oligosaccharides that were O linked to serine and/or threonine. Man-(alpha 1-2)Man-ol, Rha(alpha 1-3)Man(alpha 1-2)Man-ol, Rha(alpha 1-4)GlcA(alpha 1-2)Man(alpha 1-2)Man-ol, and Rha(alpha 1-4)[Rha(alpha 1-2)] GlcA(alpha 1-2)Man(alpha 1-2)Man-ol were characterized based on methylation analysis, proton magnetic resonance and fast atom bombardment mass spectrometry.
