FunFam 34141: Reticulon-4-interacting protein 1, mitochondrial

There are 2 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
NADPH:quinone reductase. [EC: 1.6.5.5]
NADPH + 2 quinone = NADP(+) + 2 semiquinone.
  • Specific for NADPH.
  • Catalyzes the one-electron reduction of certain quinones, with the orthoquinones 1,2-naphthoquinone and 9,10-phenanthrenequinone being the best substrates.
  • Dicoumarol (cf. EC 1.6.5.2) and nitrofurantoin are competitive inhibitors with respect to the quinone substrate.
  • The semiquinone free-radical product may be non-enzymically reduced to the hydroquinone or oxidized back to quinone in the presence of O(2).
  • Abundant in the lens of the eye of some mammalian species.

2-methylene-furan-3-one reductase. [EC: 1.3.1.105]
4-hydroxy-2,5-dimethylfuran-3(2H)-one + NAD(P)(+) = 4-hydroxy-5-methyl-2- methylenefuran-3(2H)-one + NAD(P)H.
  • In the fruit-ripening process of strawberry (Fragaria x ananassa) the reaction is catalyzed in the reverse direction from that shown.
  • 4-hydroxy-2,5-dimethylfuran-3(2H)-one is one of the major aroma compounds in the fruits.
  • The enzyme has also been detected in tomato (Solanum lycopersicum) fruits.
  • NADPH is the preferred cofactor.
