Heparinase II/III-like protein. This family features sequences that are similar to a region of the Flavobacterium heparinum proteins heparinase II and heparinase III. The former is known to degrade heparin and heparin sulphate, whereas the latter predominantly degrades heparin sulphate. Both are secreted into the periplasmic space upon induction with heparin.
Domain of unknown function (DUF4962). This family consists of uncharacterized proteins around 870 residues in length and is mainly found in various Bacteroides species. The function of this protein is unknown.
D-glucuronyl C5-epimerase C-terminus. This family represents the C-terminus of D-glucuronyl C5-epimerase (EC:5.1.3.-). Glucuronyl C5-epimerases catalyze the conversion of D-glucuronic acid (GlcUA) to L-iduronic acid (IdceA) units during the biosynthesis of glycosaminoglycans.
