Two oligosaccharides, Rha-(1→3)-GlcNAc and Gal-Rha-(1→3)-GlcNAc, were identified by gas chromatography-mass spectrometry in acid hydrolysates of arabinogalactan containing defective peptidoglycan polymer obtained from stepwise alkaline degradations of N. rubra AN-115 walls. The arabinogalactan of N. rubra AN-115 walls contained not only Ara and Gal but also Rha, while peptidoglycan contained glycan polymers composed of GlcNAc-MurNG1 units. These findings strongly suggest that arabinogalactan was linked glycosidically to peptidoglycan through a Rha-GlcN Ac linkage in N. rubra AN-115 walls.", }
