Arabinogalactan endo-beta-1,4-galactanase (EC 3.2.1.89, endo-1,4-beta-galactanase, galactanase, arabinogalactanase, ganB (gene)) is an enzyme with systematic name arabinogalactan 4-beta-D-galactanohydrolase.[1][2][3] This enzyme catalyses the following chemical reaction

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

This enzyme is isolated from the bacterium Bacillus subtilis.
