ID 3.2.1.89 DE arabinogalactan endo-beta-1,4-galactanase. AN arabinogalactanase. AN endo-1,4-beta-galactanase. AN galactanase. CA The enzyme specifically hydrolyzes (1->4)-beta-D-galactosidic linkages in CA type I arabinogalactans. CC -!- This enzyme, isolated from the bacterium Bacillus subtilis, CC hydrolyzes the beta(1->4) bonds found in type I plant CC arabinogalactans, which are a component of the primary cell walls of CC dicots. CC -!- The predominant product is a tetrasaccharide. cf. EC 3.2.1.181.
