IUBMB Enzyme Nomenclature


Accepted name: capsular-polysaccharide endo-1,3-α-galactosidase

Reaction: Random hydrolysis of (1→3)-α-D-galactosidic linkages in Aerobacter aerogenes capsular polysaccharide

Other name(s): polysaccharide depolymerase; capsular polysaccharide galactohydrolase

Systematic name: Aerobacter-capsular-polysaccharide galactohydrolase

Comments: Hydrolyses the galactosyl-α-1,3-D-galactose linkages only in the complex substrate, bringing about depolymerization.
