Arabinogalactan endo-β-1,4-galactanase

Arabinogalactan endo-β-1,4-galactanase (, endo-1,4-β-galactanase, galactanase, arabinogalactanase, ganB (gene)) is an enzyme with systematic name arabinogalactan 4-β- D -galactanohydrolase. It specifically catalyses the hydrolysis (1→4)-β- D -galactosidic linkages in type I arabinogalactans.

It is isolated from the bacterium Bacillus subtilis.
