Sentence |
denotes |
An extracellular fungal polysaccharide composed of 2-acetamido-2-deoxy-D-glucuronic acid residues. |
| TextSentencer_T2 |
99-338 |
Sentence |
denotes |
The black yeast-like fungus NRRL YB-4163, now tentatively identified as Rhinocladiella elatior Mangenot, has been found to produce an extracellular microbial polysaccharide composed mainly of 2-acetamido-2-deoxy-D-glucuronic acid residues. |
| TextSentencer_T3 |
339-532 |
Sentence |
denotes |
Polysaccharide (PS) YB-4163, when isolated in good yield as the neutral potassium salt, dissolves readily in water to produce extremely viscous solutions, which form stable foams and emulsions. |
| TextSentencer_T4 |
533-760 |
Sentence |
denotes |
By depolymerizing PS YB-4163 with [14C]methanol-HCl, the polysaccharide can be both identified and quantitated radiochemically by determining the individual [14C]methyl glycosides after their separation by paper chromatography. |
| TextSentencer_T5 |
761-905 |
Sentence |
denotes |
When the methyl glycosides of PS YB-4163 were reduced with NaB3H4, only the methyl glycosides of 2-acetamido-2-deoxy-D-[6-3H]glucose were found. |
| TextSentencer_T6 |
906-1091 |
Sentence |
denotes |
Analysis of the monosaccharide released from carboxyl-reduced PS YB-4163 by acid hydrolysis or methanolysis also showed 2-acetamido-2-deoxy-D-glucuronic acid to be the main constituent. |
| TextSentencer_T7 |
1092-1226 |
Sentence |
denotes |
Previously, the only polysaccharides known to be composed entirely or hexosaminuronic acid have been cellular products from pathogens. |
| TextSentencer_T8 |
1227-1442 |
Sentence |
denotes |
Of these, the antigenic polysaccharide (SPSA) from Staphylococcus aureus is composed entirely of 2-amino-2-deoxy-D-glucuronic acid, but its amino groups are substituted equally with acetyl and N-acetylalanyl groups. |
| TextSentencer_T9 |
1443-1651 |
Sentence |
denotes |
The specific optical rotation of PS YB-4163, [alpha]20D -75 degrees (c 0.5, water), is similar to that of SPSA (-91 degrees), and suggests beta-D-linkages that must be either (1 leads to 3) or (1 leads to 4). |
