Aldehyde ferredoxin oxidoreductase, domain 2 (IPR013984)

Short name: Ald_Fedxn_OxRdtase_dom2

Overlapping entries


Enzymes of the aldehyde ferredoxin oxidoreductase (AOR) family [PMID: 9242907] contain a tungsten cofactor and an 4Fe4S cluster and catalyse the interconversion of aldehydes to carboxylates [PMID: 8672295]. This family includes AOR, formaldehyde ferredoxin oxidoreductase (FOR), glyceraldehyde-3-phosphate ferredoxin oxidoreductase (GAPOR), all isolated from hyperthermophilic archea [PMID: 9242907]; carboxylic acid reductase found in clostridia [PMID: 2550230]; and hydroxycarboxylate viologen oxidoreductase from Proteus vulgaris, the sole member of the AOR family containing molybdenum [PMID: 8026480]. GAPOR may be involved in glycolysis [PMID: 7721730], but the functions of the other proteins are not yet clear. AOR has been proposed to be the primary enzyme responsible for oxidising the aldehydes that are produced by the 2-keto acid oxidoreductases [PMID: 9275170].

This superfamily represents an alpha-helical domain which is involved in binding the tungsten cofactor, and also contains an iron-sulphur cluster [PMID: 10024458].
