Protein

Glutaminase liver isoform, mitochondrial

Gene

Gls2

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Plays an important role in the regulation of glutamine catabolism. Promotes mitochondrial respiration and increases ATP generation in cells by catalyzing the synthesis of glutamate and alpha-ketoglutarate. Increases cellular anti-oxidant function via NADH and glutathione production (By similarity).By similarity

Catalytic activityi

L-glutamine + H2O = L-glutamate + NH3.
