Arabinogalactan endo-β-1,4-galactanase (EC 3.2.1.89, endo-1,4-β-galactanase, galactanase, arabinogalactanase, ganB (gene)) is an enzyme with systematic name arabinogalactan 4-β-D-galactanohydrolase.[1][2][3] It specifically catalyses the hydrolysis (1→4)-β-D-galactosidic linkages in type I arabinogalactans.

It is isolated from the bacterium Bacillus subtilis.
