| Comment(s) |
|---|
- Catalyzes the final step in the biosynthesis of L-ascorbic acid in
higher plants and in nearly all higher animals with the exception of
primates and some birds.
- Very specific for its substrate L-galactono-1,4-lactone as
D-galactono-gamma-lactone, D-gulono-gamma-lactone, L-gulono-gamma-
lactone, D-erythronic-gamma-lactone, D-xylonic-gamma-lactone,
L-mannono-gamma-lactone, D-galactonate, D-glucuronate and D-gluconate
are not substrates.
- FAD, NAD(+), NADP(+) and O(2) (cf. EC 1.3.3.12) cannot act as
electron acceptor.
