Glutaminase is an amidohydrolase enzyme (EC 3.5.1.2) that catalyzes the hydrolysis of glutamine, its primary substrate, into glutamate and ammonia. This crucial enzymatic action plays a key role in nitrogen metabolism, energy production, and neurotransmitter synthesis within various tissues.
Reported Benefits (Provisional)
Origin & History
Glutaminase is an enzyme that catalyzes the hydrolysis of glutamine to glutamate and ammonia. Found in various tissues, particularly the kidneys, liver, and brain, it plays a critical role in nitrogen metabolism, acid-base balance, and neurotransmitter production. Glutaminase is also significant in cellular energy production and has applications in food processing and pharmaceutical research.
Research Narrative (Provisional)
Glutaminase has been extensively studied for its roles in nitrogen metabolism, neurotransmitter synthesis, and its implications in cancer research. Research also highlights its application in food processing for flavor enhancement and its broader utility in biotechnology.

Nutritional Profile
- Enzyme Activity: Catalyzes the hydrolysis of glutamine to glutamate and ammonia, supporting metabolic and biosynthetic pathways. - Biological Role: Functions in neurotransmission, nitrogen metabolism, and cellular energy production. - Industrial Use: Enhances umami flavor in food processing and has applications in biotechnology. - Substrate Specificity: Highly specific for glutamine.
Reported Mechanism (Provisional)
Glutaminase catalyzes the hydrolysis of glutamine into glutamate and ammonia, primarily within the mitochondrial matrix. Glutamine binds to the enzyme's active site where a proton facilitates the cleavage of the amide bond, releasing ammonia and subsequently yielding glutamate. This newly formed glutamate can then feed into the tricarboxylic acid (TCA) cycle via glutamate dehydrogenase, contributing to cellular energy production.
Clinical Narrative (Provisional)
Research on glutaminase largely focuses on its fundamental biological roles in nitrogen metabolism, neurotransmitter synthesis, and its critical involvement in cellular energetics. Numerous *in vitro* and *in vivo* (animal) studies have elucidated its mechanisms and tissue-specific expression, particularly in kidneys, liver, and brain. While its implications in cancer metabolism are extensively studied, specific human clinical trials evaluating exogenous glutaminase for general health benefits are not widely documented. Its therapeutic potential in diseases like cancer often involves inhibiting the enzyme rather than supplementing it.
