Change Type: Corrigendum

Change Details: In the version of this article initially published, there were errors in two figures. The schematic in Figure 4a was mistakenly drawn with a β1→3 linkage between the –1 GlcUA and the +1 GlcNS(6S), rather than the correct β1→4 linkage. Supplementary Figure 1 incorrectly gave the names of the GlcNX monomers as N -acetyl-α- D -glucuronic acid and N -sulfo-α- D -glucuronic acid, rather than N -acetyl-α- D -glucosamine and N -sulfo- α- D -glucosamine. These errors have been corrected in the HTML and PDF versions of the article.
