Abstract
The present invention discloses a glycosylated oxalate decarboxylase. The oxalate decarboxylase is derived from edible basidiomycetes, the glycosylated oxalate decarboxylase has an enzyme activity at the pH value of 1.5-7.5, the activity at the pH value of 1.5-2.0 is 10% greater than the optimum activity, and a specific activity is more than 2 U/mg. The present invention also discloses preparation and application of the glycosylated oxalate decarboxylase. The glycosylated oxalate decarboxylase disclosed by the present invention can keep the activity under a low pH value, and can effectively prevent and treat kidney stones.
