Figure 6
Hypothetical model showing some proposed interactions between the terminal N-sulfoglucosamine residue (GlcNS; C atoms in green, other atoms in standard colours) of the substrate with the enzyme in the active site (C atoms in light grey). His181 acts as the acid facilitating desulfation of the substrate. Other residues that help to bind and orient the substrate include the side chains of FGly70, Lys123, Arg282 and His368 and the main-chain amide N atom of Asp401.
