A Revised Structure for the Glycolipid Terminus of <i>Escherichia coli</i> K5 Heparosan Capsular Polysaccharide.
Biomolecules 20201106 11
The structure of heparosan capsular polysaccharide (CPS) has been determined using enzymatic digestion with nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. Previous errors in the assignment of the glycolipid acceptor structure, from which heparosan is extended, have been corrected. The structure of heparosan CPS is GlcNAc <i>α</i>-1,[4GlcA <i>β</i>-1,4GlcNAc <i>α</i>-1,]<sub>n</sub>4GlcA <i>β</i>-1,[4Kdo <i>β</i>-2,7Kdo <i>β</i>-2,]<sub>0 or 1</sub>4Kdo <i>β</i>-2,7Kdo <i>β< ...[more]
