1.3.3.12 |
Accepted name: |
L-galactonolactone oxidase |
Reaction: |
L-galactono-1,4-lactone + O2 = L-ascorbate + H2O2 |
Other name(s): |
L-galactono-1,4-lactone oxidase |
Systematic name: |
L-galactono-1,4-lactone:oxygen 3-oxidoreductase |
Comments: |
A flavoprotein. Acts on the 1,4-lactones of L-galactonic, D-altronic, L-fuconic, D-arabinic and D-threonic acids; not identical with EC 1.1.3.8 L-gulonolactone oxidase. (cf. EC 1.3.2.3 galactonolactone dehydrogenase). |
