Note that this reaction equation differs from the official Enzyme Commission reaction equation for this EC number, which can be found here .
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: polar-amino-acid-transporting ATPase
Enzyme Commission Synonyms: histidine permease
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. Comprises bacterial enzymes that import His, Arg, Lys, Glu, Gln, Asp, ornithine, octopine and nopaline.
