EC Number: 3.6.3.34

Transporters and Genes:
ferric dicitrate ABC transporter Inferred from experiment Inferred by computational analysis : fecE , fecC , fecD , fecB

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 Enzyme Commission system.

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.
