Accumulated data from spectroscopic (<jats:sup>13<\/jats:sup>C and <jats:sup>1<\/jats:sup>H nuclear magnetic resonance) and methylation analyses of the native and specifically degraded polysaccharide indicated that it was linear and composed of the following pentasaccharide repeating unit; \u20144)-\u03b1-D-GlcpA-(1\u2002\u2192\u20023)-\u03b1-D-Glcp-(1\u2002\u2192\u20023)-\u03b2-D-ManpNAc-(1\u2002\u2192\u20024)-\u03b1-D-Glcp-(1\u2002\u2192\u20024)-\u03b2-D-GlcpNAc(1\u2002\u2192.
