Displays glyoxalase activity, catalyzing the conversion of glyoxal to glycolate. However, this apparent glyoxalase activity may reflect a deglycase activity, which could be the primary function of this protein like other DJ-1 superfamily members such as PARK7, YajL, YhbO and HchA. Is not able to use methylglyoxal as substrate. glyoxal + H2O = glycolate + H(+) Homodimer. Belongs to the peptidase C56 family.
