Enzyme Information
| 5.6.1.6 |
Channel-conductance-controlling ATPase.
based on mapping to UniProt P26361
ATP + H(2)O + closed Cl(-) channel = ADP + phosphate + open Cl(-) channel.
-!- ABC-type (ATP-binding cassette-type) ATPase, characterized by the presence of two similar ATP-binding domains. -!- The enzyme is found in animals, and in humans its absence brings about cystic fibrosis. -!- Unlike most of the ABC transporters, chloride pumping is not directly coupled to ATP hydrolysis. -!- Instead, the passive flow of anions through the channel is gated by cycles of ATP binding and hydrolysis by the ATP-binding domains. -!- The enzyme is also involved in the functioning of other transmembrane channels. -!- Formerly EC 3.6.3.49.
