This domain is found centrally in D-glucuronyl C5-epimerase from humans (Glce) and similar proteins involved in glycan metabolism and heparin biosynthesis in animals. Glce is essential for the reversible epimerisation of D-glucuronic acid (GlcA) into L-iduronic acid (IdoA), contributing to generate functional protein-binding motifs to ensure polymer function. This protein consists of three intertwined domains. This entry represents a classical beta-sandwich domain that consists predominantly of a convex four-stranded beta- -sheet and a concave seven-stranded beta-sheet. It is inserted between two of the helices of the C-terminal alpha-barrel domain (whose most C-terminal region is represented by Pfam:PF06662) [1,2].
