| 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.
