Chains	Enzyme Name	Description	Catalytic Residues
A	arabinogalactan endo-1,4-beta-galactosidase M-CSA #658	Asperfillus aculeatus beta-1,4-Galactanase (AAGAL) is an enzyme involved in pectin degradation. It belongs to the glycoside hydrolase family 53 (GH-53) in clan GH-A. It catalyses the endohydrolysis of beta-1,4-linked galactan and type I arabinogalactan to galactose and galactose oligomers. Galactan and arabinogalactan are components of pectin which attaches to the C4 position of rhamnose. They forms the side-chains of the 'hairy' region of pectin. Degradation and modification of the galatan and arabinogalactan side chain has many industrial applications, so AAGAL has potential industrial uses.
