Reaction MAR03890 also occurs in mitochondria

[liamkelley93]

The enzyme responsible for generation of glutamine from glutamate + NH3, glutamine synthetase (GS, GLUL), has known localization in both the cytosol and the mitochondria. Evidence on The Human Protein Atlas. Therefore, I would propose a mitochondria-localized duplicate of the reaction be created.

[JHL-452b]

Glutamine synthetase (GS, GLUL) is also shown to be localized in the cytoplasm and mitochondria in Uniprot.

In addition, glutamate and glutamine in mitochondria are not dead-end metabolites in Human-GEM, which means that introducing the duplicate mitochondrial reaction of MAR03890 is not a block reaction. Therefore, I agree to add this new reaction.
