This domain is found towards the C terminus of Beta-glucuronidase from Formosa agariphila (P17_GH2) and similar proteins mainly from bacteria and fungi. P17_GH2 is involved in the degradation of the polysaccharide ulvan. The function of this domain, which shows an all-beta structure, is unknown [1].	Domain
