| Note | Family created after Kopel et al. (2016) J. Biol. Chem., 291, 5871-5878 [PMID=26763234]. Ulvan lyases cleave the bond between 3-sulfated rhamnose (Rha3S) linked to either D-glucuronic acid (GlcA) or L-iduronic acid (IduA) in the marine polysaccharide ulvan. Members of this family are known to specifically cleave the b(1,4) glycosidic bond between GlcUA and R3S residues by b-elimination. |
