Accepted name: 3-deoxy-2-octulosonidase

Reaction: Endohydrolysis of the β-ketopyranosidic linkages of 3-deoxy-D-manno-2-octulosonate in capsular polysaccharides

Other name(s): 2-keto-3-deoxyoctonate hydrolase; octulosylono hydrolase; octulofuranosylono hydrolase; octulopyranosylonohydrolase

Systematic name: capsular-polysaccharide 3-deoxy-D-manno-2-octulosonohydrolase

Comments: The enzyme from a bacteriophage catalyses the depolymerization of capsular polysaccharides containing 3-deoxy-2-octulosonide in the cell wall of Escherichia coli.
