EC 220.127.116.11 - Arabinogalactan endo-β-1,4-galactanase
IntEnz Enzyme Nomenclature
ganB (gene name)
- The enzyme specifically hydrolyses (1→4)-β-D-galactosidic linkages in type I arabinogalactans.
This enzyme, isolated from the bacterium Bacillus subtilis, hydrolyses the β(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 18.104.22.168, galactan endo-β-1,3-galactanase.
