FunFam 26411: ABC transporter C family MRP4

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
Xenobiotic-transporting ATPase. [EC: 3.6.3.44]
ATP + H(2)O + xenobiotic(In) = ADP + phosphate + xenobiotic(Out).
  • Enzymes of Gram-positive bacteria and eukaryotic cells that export a number of drugs, with unusual specificity, covering various groups of unrelated substances, while ignoring some that are closely related structurally.
  • Several distinct enzymes may be present in a single eukaryotic cell.
  • Many of them transport glutathione conjugates with drugs.
  • Some also show some 'flippase' (EC 3.6.3.1) activity.
  • Formerly EC 3.6.3.45.

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).

Adenosinetriphosphatase. [EC: 3.6.1.3]
ATP + H(2)O = ADP + phosphate.
  • Many enzymes previously listed under this number are now listed separately as EC 3.6.1.32 to EC 3.6.1.39.
  • The remaining enzymes, not separately listed on the basis of some function coupled with hydrolyzes of ATP, include enzymes dependent on Ca(2+), Mg(2+), anions, H(+) or DNA.
  • Formerly EC 3.6.1.4.
