Copper amine oxidase N-terminal domain. Copper amine oxidases catalyze the oxidative deamination of primary amines to the corresponding aldehydes, while reducing molecular oxygen to hydrogen peroxide. These enzymes are dimers of identical subunits, each comprising four domains. The N-terminal domain, which is absent in some amine oxidases, consists of a five-stranded antiparallel beta sheet twisted around an alpha helix. The D1 domains from the two subunits comprise the 'stalk' of the mushroom-shaped dimer, and interact with each other but do not pack tightly against each other.

Heparinase II C-terminal domain. Heparinase II (HepII) is an 85-kDa dimeric enzyme that depolymerizes both heparin and heparan sulfate glycosaminoglycans. The protein is composed of three domains: an N-terminal alpha-helical domain, a central two-layered beta-sheet domain, and a C-terminal domain forming a two-layered beta-sheet. The C-terminal domain contains nine beta-strands packed together in a manner resembling a beta-barrel.

F5/8 type C domain. This domain is also known as the discoidin (DS) domain family.

Carbohydrate Binding Module 35 (CBM35); appended to several carbohydrate binding enzymes, including several glycoside hydrolase (GH) family 26 mannanase domains. This family includes carbohydrate binding module 35 (CBM35) domains that are appended to several carbohydrate binding enzymes, including periplasmic component of ABC-type sugar transport system involved in carbohydrate transport and metabolism, and several glycoside hydrolase (GH) domains, including GH26. These CBM6s are non-catalytic carbohydrate binding domains that facilitate the strong binding of the GH catalytic modules with their dedicated, insoluble substrates. Examples of proteins having CMB35s belonging to this family are mannanase A from Clostridium thermocellum (GH26), Man26B from Paenibacillus sp. BME-14 (GH26), and the multifunctional Cel44C-Man26A from Paenibacillus polymyxa GS01 (which has two GH domains, GH44 and GH26). GH26 mainly includes mannan endo-1,4-beta-mannosidase which hydrolyzes 1,4-beta-D-linkages in mannans, galacto-mannans, glucomannans, and galactoglucomannans, but displays little activity towards other plant cell wall polysaccharides. A few proteins belonging to this family have additional CBM3 domains; these CBM3s are not found in the CBM6-CBM35-CBM36_like superfamily.
