Accepted name: (methyl)glyoxal oxidase
Reaction: (1) glyoxal + H2O + O2 = glyoxylate + H2O2
(2) 2-oxopropanal + H2O + O2 = pyruvate + H2O2
Glossary: 2-oxopropanal = methylglyoxal
Other name(s): glx1 (gene name); glx2 (gene name)
Systematic name: (methyl)glyoxal:oxygen oxidoreductase
Comments: The enzyme, originally characterized from the white rot fungus Phanerochaete chrysosporium, utilizes a free radical-coupled copper complex for catalysis.
