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.

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

Domain of unknown function (DUF4962). This family consists of uncharacterized proteins around 870 residues in length and is mainly found in various Bacteroides species. The function of this protein is unknown.

Heparinase II/III-like protein. This family features sequences that are similar to a region of the Flavobacterium heparinum proteins heparinase II and heparinase III. The former is known to degrade heparin and heparin sulphate, whereas the latter predominantly degrades heparin sulphate. Both are secreted into the periplasmic space upon induction with heparin.
