IUBMB Enzyme Nomenclature


Accepted name: β-galactofuranosidase

Reaction: Hydrolysis of terminal non-reducing β-D-galactofuranosides, releasing galactose

Other name(s): exo-β-galactofuranosidase; exo-β-D-galactofuranosidase; β-D-galactofuranosidase

Systematic name: β-D-galactofuranoside hydrolase

Comments: The enzyme from Helminthosporium sacchari detoxifies helminthosporoside, a bis(digalactosyl)terpene produced by this fungus, by releasing its four molecules of bound galactose.
