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.
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.
DNA alkylation repair enzyme. Proteins in this family are predicted to be DNA alkylation repair enzymes. The structure of a hypothetical protein in this family shows it to adopt a supercoiled alpha helical structure.
