General annotation (Comments)

Function

Oxidizes L-gulono-1,4-lactone to hydrogen peroxide and L-xylo-hexulonolactone which spontaneously isomerizes to L-ascorbate By similarity. UniProtKB P10867

Catalytic activity

L-gulono-1,4-lactone + O2 = L-xylo-hex-2-ulono-1,4-lactone + H2O2.

L-xylo-hex-2-ulono-1,4-lactone = L-ascorbate.

Cofactor

FAD By similarity. UniProtKB P10867

Pathway

Cofactor biosynthesis; L-ascorbate biosynthesis via UDP-alpha-D-glucuronate pathway; L-ascorbate from UDP-alpha-D-glucuronate: step 4/4.

Subcellular location

Microsome membrane; Single-pass membrane protein By similarity. Endoplasmic reticulum membrane; Single-pass membrane protein By similarity.

Sequence similarities

Belongs to the oxygen-dependent FAD-linked oxidoreductase family.

Contains 1 FAD-binding PCMH-type domain.
