endo-1,4-beta-galactanase;
galactanase (ambiguous);
arabinogalactanase;
ganB (gene name)
|

| Class |
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
 |

| Sysname |
arabinogalactan 4-beta-D-galactanohydrolase
|
|---|
| Reaction(IUBMB) |
The enzyme specifically hydrolyses (1->4)-beta-D-galactosidic linkages in type I arabinogalactans.
|
|---|
| Comment |
This enzyme, isolated from the bacterium Bacillus subtilis, hydrolyses 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, galactan endo-beta-1,3-galactanase.
