FunFam 290648: Putative NADP-dependent oxidoreductase P1

There are 5 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
2-alkenal reductase (NAD(P)(+)). [EC: 1.3.1.74]
A n-alkanal + NAD(P)(+) = an alk-2-enal + NAD(P)H.
  • Highly specific for 4-hydroxynon-2-enal and non-2-enal.
  • Alk-2-enals of shorter chain have lower affinities.
  • Exhibits high activities also for alk-2-enones such as but-3-en-2-one and pent-3-en-2-one.
  • Inactive with cyclohex-2-en-1-one and 12-oxophytodienoic acid.
  • Involved in the detoxification of alpha,beta-unsaturated aldehydes and ketones (cf. EC 1.3.1.102).

DNA helicase. [EC: 3.6.4.12]
ATP + H(2)O = ADP + phosphate.
  • DNA helicases utilize the energy from ATP hydrolysis to unwind double-stranded DNA.
  • Some of them unwind duplex DNA with a 3' to 5' polarity (1,3,5,8), other show 5' to 3' polarity (10,11,12,13) or unwind DNA in both directions (14,15).
  • Some helicases unwind DNA as well as RNA (4,9).
  • May be identical with EC 3.6.4.13 (RNA helicase).
 4 L7IHI2 L7IHI2 L7JA43 L7JA43
15-oxoprostaglandin 13-reductase. [EC: 1.3.1.48]
11-alpha-hydroxy-9,15-dioxoprost-5-enoate + NAD(P)(+) = (5Z)-(13E)-11- alpha-hydroxy-9,15-dioxoprosta-5,13-dienoate + NAD(P)H.
  • Reduces 15-oxoprostaglandins to 13,14-dihydro derivatives.
  • The enzyme from placenta is specific for NAD(+).
 4 A2R334 A2R334 G3XPE7 G3XPE7
(+)-pulegone reductase. [EC: 1.3.1.81]
(1) (-)-menthone + NADP(+) = (+)-pulegone + NADPH. (2) (+)-isomenthone + NADP(+) = (+)-pulegone + NADPH.
  • NADH cannot replace NADPH as reductant.
  • The Delta(8,9)-double bond of (+)-cis-isopulegone and the Delta(1,2)- double bond of (+-)-piperitone are not substrates.
  • The enzyme from peppermint (Mentha x piperita) converts (+)-pulegone into both (-)-menthone and (+)-isomenthone at a ratio of 70:30 for native enzyme but it does not catalyze the reverse reaction.
 2 Q6WAU0 Q6WAU0
2-alkenal reductase (NADP(+)). [EC: 1.3.1.102]
An n-alkanal + NADP(+) = an alk-2-enal + NADPH.
  • Shows highest activity with 1-nitrocyclohexene but also has significant activity with 2-methylpentenal and trans-cinnamaldehyde.
  • Involved in the detoxification of alpha,beta-unsaturated aldehydes and ketones.
  • Has very low activity with NAD as reductant (cf. EC 1.3.1.74).
