CATH Classification

Domain Context

CATH Clusters

Superfamily P-loop containing nucleotide triphosphate hydrolases
Functional Family ABC transporter ATP-binding protein/permease

Enzyme Information

3.6.3.44
Xenobiotic-transporting ATPase.
based on mapping to UniProt P21447
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.
