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

Malectin is a membrane-anchored protein of the endoplasmic reticulum that recognises and binds Glc2-N-glycan. It carries a signal peptide from residues 1-26, a C-terminal transmembrane helix from residues 255-274, and a highly conserved central part of approximately 190 residues followed by an acidic, glutamate-rich region. Carbohydrate-binding is mediated by the four aromatic residues, Y67, Y89, Y116, and F117 and the aspartate at D186. NMR-based ligand-screening studies has shown binding of the protein to maltose and related oligosaccharides, on the basis of which the protein has been designated "malectin", and its endogenous ligand is found to be Glc2-high-mannose N-glycan [1].
