3.2.1.181 | arabinogalactan + H2O |
the enzyme specifically acts on beta-1,3-galactan within the plant proteoglycansin arabinogalactan-proteins (AGPs) in an endo-manner. The carbohydrate moieties of AGPs consist of beta-1,3-galactan main chains and beta-1,6-galactan side chains, to which other auxiliary sugars are attached. Enzyme Af3G hardly hydrolyze native arabinogalactan-proteins (AGPs) alone but acts synergistically with a fungal exo-beta-1,3-galactanase on the AGP |

The carbohydrate moieties of AGPs consist of beta-1,3-galactan main chains and beta-1,6-galactan side chains, to which other auxiliary sugars are attached. Enzyme NcEn3GAL hardly hydrolyze native arabinogalactan-proteins (AGPs) alone but acts synergistically with a fungal exo-beta-1,3-galactanase on the AGP. Very low activity on native gum arabic and the larch arabinogalactan |
