Alpha-glucuronidases, components of an ensemble of enzymes central to the recycling of photosynthetic biomass, remove the alpha-1,2 linked 4-O-methyl glucuronic acid from xylans. This family represents the N-terminal region of alpha-glucuronidase. The N-terminal domain forms a two-layer sandwich, each layer being formed by a beta sheet of five strands. A further two helices form part of the interface with the central, catalytic, module (Pfam:PF07488) [1].	Domain

Alpha-glucuronidases, components of an ensemble of enzymes central to the recycling of photosynthetic biomass, remove the alpha-1,2 linked 4-O-methyl glucuronic acid from xylans. This family represents the C terminal region of alpha-glucuronidase which is mainly alpha-helical. It wraps around the catalytic domain (Pfam:PF07488), making additional interactions both with the N-terminal domain (Pfam:PF03648) of its parent monomer and also forming the majority of the dimer-surface with the equivalent C-terminal domain of the other monomer of the dimer [1].
