Subcellular LocationPeriplasm
FunctionGAG lyase. It acts in an endolytic manner and displays broad selectivity, catalyzing the cleavage of linkages adjacent not only to IdoA and GlcA but also to the rare -L-galacturonic acid residues present in the polymer. Although HepII has greater affinity for heparin, its turnover rate for heparan sulfate is higher.

Glycan Information
Glycan AnnotationLinkage: Man-Thr.
Tetrasaccharide glycan observed in crystal structure: Man-(Rha)-GlcUA-Xyl (xylose-β (1–4)glucuronic acid-α(1–2)[rhamnose-α(1–4)]mannose-α(1-O)Ser. Two more sugars were visible but their density was too weak to be reliably modeled. The branched Rha sugar fills a depression in the protein surface while the remaining sugars extend away from the surface of the protein.
