EC Number: 18.104.22.168
Note that this reaction equation differs from the official Enzyme Commission reaction equations for this EC number.
Reaction Locations: inner membrane (sensu Gram-negative Bacteria)
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: iron-chelate-transporting ATPase
Enzyme Commission Synonyms:
Enzyme Commission Summary:
ABC-type (ATP-binding cassette-type) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports Fe-enterobactin, Fe-dicitrate, Fe-hydroxamate and other siderophores.
