3.2.1.146

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.
