  2. L-glutaminase
  3. L-glutamine amidohydrolase
  4. SubName: L-glutaminase
Gene Name GLS2
Protein Type Enzyme
Biological Properties
General Function Involved in glutaminase activity
Specific Function 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. May play a role in preventing tumor proliferation.
