ENZYME entry: EC 3.2.1.214

Accepted Name
exo beta-1,2-glucooligosaccharide sophorohydrolase (non-reducing end)
Reaction catalysed
[(1->2)-beta-D-glucosyl](n) + H2O = [(1->2)-beta-D-glucosyl](n-2) + sophorose
Comment(s)
  • The enzyme, characterized from the bacterium Parabacteroides distasonis, specifically hydrolyzes (1->2)-beta-D- glucooligosaccharides to sophorose.
  • The best substrates are the tetra- and pentasaccharides.
  • The enzyme is not able to cleave the trisaccharide, and activity with longer linear (1->2)-beta-D-glucans is quite low.
  • This enzyme acts in exo mode and is not able to hydrolyze cyclic (1->2)-beta-D-glucans.
