Glycosyl hydrolase family 115. Glyco_hydro_115 is a family of glycoside hydrolases likely to have the activity of xylan a-1,2-glucuronidase, EC:3.2.1.131, or a-(4-O-methyl)-glucuronidase EC:3.2.1.-.

Gylcosyl hydrolase family 115 C-terminal domain. This domain is found at the C-terminus of glycosyl hydrolase family 115 proteins. This domain has a beta-sandwich fold.

Bacteroidetes-Associated Carbohydrate-binding (putative) Often N-terminal (BACON) domain. The BACON domain is found in diverse domain architectures and accociated with a wide variety of domains, including carbohydrate-active enzymes and proteases. It was named for its suggested function of carbohydrate binding; the latter was inferred from domain architectures, sequence conservation, and phyletic distribution. However, recent experimental data suggest that its primary function in Bacteroides ovatus endo-xyloglucanase BoGH5A is to distance the catalytic module from the cell surface and confer additional mobility to the catalytic domain for attack of the polysaccharide. No evidence for a direct role in carbohydrate binding could be found in that case. The large majority of BACON domains are found in Bacteroidetes.

Glycosyl hydrolase family 67 N-terminus. 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 (pfam07488).
