抄録

An extracellular, acidic polysaccharide was isolated from a marine strain of Enterobacter sp., designed MU-3, which was tentatively identified as E. agglomerans. The structure of this polysaccharide was determined by techniques of methylation, mild acid hydrolysis, periodate oxidation, Smith hydrolysis, and β-elimination. ¹H and ¹³C NMR spectroscopy was used to establish the nature of the anomeric linkages of the polysaccharide and of oligosaccharides derived through degradative procedures. The polysaccharide has a branched structure containing a backbone chain of →3)-β-D-Galp (1→3)-α-D-Galp (1→6)-β-D-Glcp (1→, and a side chain of α-D-Galp (1→4)-β-D-GlcUAp (l→. The glucuronic acid residue in the side chain joins through C-4, to β-D-galactose residue in the main chain. The terminal galactose in the side chain bears a pyruvic acetal substituent at positions C-4 and C-6.
