Enzyme Information

3.2.1.89

Arabinogalactan endo-beta-1,4-galactanase.

based on mapping to UniProt P83691

The enzyme specifically hydrolyzes (1->4)-beta-D-galactosidic linkages in type I arabinogalactans.

-!- This enzyme, isolated from the bacterium Bacillus subtilis, hydrolyzes the beta(1->4) bonds found in type I plant arabinogalactans, which are a component of the primary cell walls of dicots. -!- The predominant product is a tetrasaccharide. -!- Cf. EC 3.2.1.181.
