FunFam 39773: 4Fe-4S ferredoxin, iron-sulfur binding

There are 4 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
NADH dehydrogenase. [EC: 1.6.99.3]
NADH + acceptor = NAD(+) + reduced acceptor.
  • After preparations have been subjected to certain treatments cytochrome c may act as acceptor.
  • Under normal conditions, two protons are extruded from the cytoplasm or the intramitochondrial or stromal compartment.
  • Present in a mitochondrial complex as EC 1.6.5.3.
  • Formerly EC 1.6.2.1.

Allophanate hydrolase. [EC: 3.5.1.54]
Urea-1-carboxylate + H(2)O = 2 CO(2) + 2 NH(3).
  • Along with EC 3.5.2.15 and EC 3.5.1.84, forms part of the cyanuric- acid metabolism pathway, which degrades s-triazide herbicides, such as atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-1,3,5- triazine), in bacteria.
  • The Saccharomyces cerevisiae enzyme (but not that from green algae) also catalyzes the reaction of EC 6.3.4.6, thus bringing about the hydrolysis of urea to CO(2) and NH(3) in the presence of ATP and bicarbonate.
  • The enzyme from Pseudomonas sp. strain ADP has a narrow substrate specificity, being unable to use the structurally analogous compounds urea, hydroxyurea or methylcarbamate as substrate.

NADH:ubiquinone reductase (H(+)-translocating). [EC: 1.6.5.3]
NADH + ubiquinone + 5 H(+)(In) = NAD(+) + ubiquinol + 4 H(+)(Out).
  • The complex is present in mitochondria and aerobic bacteria.
  • Breakdown of the complex can release EC 1.6.99.3.
  • In photosynthetic bacteria, reversed electron transport through this enzyme can reduce NAD(+) to NADH.
4 A0A1J0NQ46 A0A1J0NQ46 I2AZV5 I2AZV5
Ferredoxin hydrogenase. [EC: 1.12.7.2]
H(2) + 2 oxidized ferredoxin = 2 reduced ferredoxin + 2 H(+).
  • Can use molecular hydrogen for the reduction of a variety of substances.
  • Formerly EC 1.12.1.1, EC 1.12.7.1, EC 1.18.3.1, EC 1.18.99.1, and EC 1.98.1.1.
