- 3-deoxyoctulosonyl-lipopolysaccharide + H2O 3-deoxyoctulosonic acid + lipopolysaccharide
Thus, the two substrates of this enzyme are 3-deoxyoctulosonyl-lipopolysaccharide and H2O, whereas its two products are 3-deoxyoctulosonic acid and lipopolysaccharide.
This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is 3-deoxyoctulosonyl-lipopolysaccharide hydrolase. This enzyme is also called alpha-Kdo-ase.
