Heparin lyase I depolymerises heparin by cleaving the glycosidic linkage next to an iduronic acid moiety [1,2]. The structure of heparin lyase I consists of a beta-jelly roll domain with a long, deep substrate-binding groove and an unusual thumb domain containing many basic residues extending from the main body of the enzyme [2]. This family also includes glucuronan lyase, EC:4.2.2.14 [3]. The structure glucuronan lyase is a beta-jelly roll [4].
