FunFam 12100: D-Arabinono-1,4-lactone oxidase (Eurofung)

There are 5 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
L-gulonolactone oxidase. [EC: 1.1.3.8]
L-gulono-1,4-lactone + O(2) = L-ascorbate + H(2)O(2).
  • The product spontaneously isomerizes to L-ascorbate.
  • While most higher animals can synthesize ascorbic acid, primates and guinea pigs cannot.

Alditol oxidase. [EC: 1.1.3.41]
An alditol + O(2) = an aldose + H(2)O(2).
  • While xylitol (five carbons) and sorbitol (6 carbons) are the preferred substrates, other alditols, including L-threitol (four carbons), D-arabinitol (five carbons), D-galactitol (six carbons) and D-mannitol (six carbons) can also act as substrates, but more slowly.

D-arabinono-1,4-lactone oxidase. [EC: 1.1.3.37]
D-arabinono-1,4-lactone + O(2) = dehydro-D-arabinono-1,4-lactone + H(2)O(2).

    L-galactonolactone dehydrogenase. [EC: 1.3.2.3]
    L-galactono-1,4-lactone + 4 ferricytochrome c = L-dehydroascorbate + 4 ferrocytochrome c + 4 H(+).
    • 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.

    (10 more...)
    UDP-N-acetylmuramate dehydrogenase. [EC: 1.3.1.98]
    UDP-N-acetyl-alpha-D-muramate + NADP(+) = UDP-N-acetyl-3- O-(1-carboxyvinyl)-alpha-D-glucosamine + NADPH.
    • NADH can to a lesser extent replace NADPH.
    • Formerly EC 1.1.1.158.
