FunFam 20: Xanthine dehydrogenase iron-sulfur subunit

There are 3 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
Carboxylate reductase. [EC: 1.2.99.6]
An aldehyde + acceptor + H(2)O = a carboxylate + reduced acceptor.
  • Methylviologen can act as acceptor.
  • In the reverse direction, non-activated acids are reduced by reduced viologens to aldehydes, but not to the corresponding alcohols.

Glyceraldehyde dehydrogenase (FAD-containing). [EC: 1.2.99.8]
D-glyceraldehyde + H(2)O + acceptor = D-glycerate + reduced acceptor.
  • The enzyme from the archaeon Sulfolobus acidocaldarius catalyzes the oxidation of D-glyceraldehyde in the nonphosphorylative Entner- Doudoroff pathway.
  • With 2,6-dichlorophenolindophenol as artificial electron acceptor, the enzyme shows a broad substrate range, but is most active with D-glyceraldehyde.
  • It is not known which acceptor is utilized in vivo.

Caffeine dehydrogenase. [EC: 1.17.5.2]
Caffeine + ubiquinone + H(2)O = 1,3,7-trimethylurate + ubiquinol.
  • This enzyme, characterized from the soil bacterium Pseudomonas sp. CBB1, catalyzes the incorporation of an oxygen atom originating from a water molecule into position C-8 of caffeine.
  • The enzyme utilizes short-tail ubiquinones as the preferred electron acceptor.
