| 3.2.1.164 | arabinogalactan + H2O |
plant type II arabinogalactans consisting of beta-(1,3)- and beta-(1,6)-galactan side chains connected to each other by (1,3)(1,6)-linked branch points. The O-3 and O-6 positions are substituted with terminal arabinosyl residues |

| 3.2.1.164 | arabinogalactan-protein + H2O |
the enzyme prefers alpha-L arabinofuranosidase-treated arabinogalactan-proteins from radish roots (151% activity) and radish leaves (87% activity) compared to native ones from radish roots (36% activity) and leaves (28% activity) |

| 3.2.1.164 | beta-galactan + H2O |
galactan from Prototheca zopfii, which has a high proportion of beta-1,6-linked galactosyl residues, the extent of hydrolysis of the carbohydrate portion of a radish root arabinogalactan-protein AGP increases when alpha-L-arabinofuranosyl residues attached to beta-1,6-linked galactosyl side chains of the AGP are removed in advance, the enzyme releases galactose, beta-1,6-galactobiose, and 4-O-methyl-beta-glucuronosyl-1,6-galactose as major hydrolysis products when allowed to act exhaustively on the modified AGP, overview |
