FunFam 7799: Monodehydroascorbate reductase, seedling isozyme

There are 6 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
Ferredoxin--NAD(+) reductase. [EC: 1.18.1.3]
Reduced ferredoxin + NAD(+) = oxidized ferredoxin + NADH.
  • The reaction is written for a [2Fe-2S] ferredoxin, which is characteristic of some mono- and dioxygenase systems.
  • some anaerobic bacteria have a 2[4Fe-4S] ferredoxin, which transfers two electrons.

Monodehydroascorbate reductase (NADH). [EC: 1.6.5.4]
NADH + 2 monodehydroascorbate = NAD(+) + 2 ascorbate.

    Putidaredoxin--NAD(+) reductase. [EC: 1.18.1.5]
    Reduced putidaredoxin + NAD(+) = oxidized putidaredoxin + NADH.
    • The enzyme from Pseudomonas putida reduces putidaredoxin.
    • It contains a [2Fe-2S] cluster.
    • Involved in the camphor monooxygenase system (see EC 1.14.15.1).

    DNA-(apurinic or apyrimidinic site) lyase. [EC: 4.2.99.18]
    The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.
    • 'Nicking' of the phosphodiester bond is due to a lyase-type reaction, not hydrolysis.
    • This group of enzymes was previously listed as endonucleases, under the number EC 3.1.25.2.
    		 4 A0A0B2Q6B9 A0A0B2Q6B9 B9RCH2 B9RCH2
    Nitrite reductase (NAD(P)H). [EC: 1.7.1.4]
    Ammonia + 3 NAD(P)(+) + 2 H(2)O = nitrite + 3 NAD(P)H.
    • The enzymes from the fungi Neurospora crassa, Emericella nidulans and Candida nitratophila and the bacterium Aliivibrio fischeri can use either NADPH or NADH as electron donor.
    • Cf. EC 1.7.1.15.
    • Formerly EC 1.6.6.4.
    		 4 A0A100I9H1 A0A100I9H1 L7V3S5 L7V3S5
    Ferredoxin--NADP(+) reductase. [EC: 1.18.1.2]
    2 reduced ferredoxin + NADP(+) + H(+) = 2 oxidized ferredoxin + NADPH.
    • In chloroplasts and cyanobacteria the enzyme acts on plant-type [2Fe- 2S] ferredoxins, but in other bacteria it can also reduce bacterial 2[4Fe-4S] ferredoxins and flavodoxin.
    • Formerly EC 1.6.7.1 and EC 1.6.99.4.
