New application of microbial l-glutaminase as a flavor enhancing agent in beef burgers
L‑glutaminase (L‑glutamine amidohydrolase EC3.5.1.2) is the key enzyme in enhancing the taste and aroma of oriental fermented foods by increasing their glutamic acid content and as a result imparting a palatable taste.

Purification and properties of L-glutaminase-L-asparaginase from Pseudomonas acidovorans [PDF]
An enzyme that catalyzes the hydrolysis of both glutamine and asparagine has been purified to homogeneity from extracts of Pseudomonas acidovorans. The enzyme having a ratio of glutaminase to asparaginase of 1.45:1.0 can be purified by a relatively simple procedure and is stable upon storage.

Engineering of Helicobacter pylori L-asparaginase: characterization of two functionally distinct groups of mutants. [PDF]
Bacterial L-asparaginases have been used as anti-cancer drugs for over 4 decades though presenting, along with their therapeutic efficacy, several side effects due to their bacterial origin and, seemingly, to their secondary glutaminase activity ...

TNF-α promotes extracellular vesicle release in mouse astrocytes through glutaminase
Background Extracellular vesicles (EVs) are membrane-contained vesicles shed from cells. EVs contain proteins, lipids, and nucleotides, all of which play important roles in intercellular communication.

L-glutaminase is gaining marked importance due to its potential clinical applications. A variety of microorganisms, including bacteria, yeast, and lamentous fungi, from soil habitat have been reported to produce L-glutaminase. The present investigation was carried out to isolate and screening of L-glutamiase producing bacteria from soil samples of ...

DL-3-n-butylphthalide enhances synaptic plasticity in mouse model of brain impairments
Synaptic impairment results in cognitive dysfunction of Alzheimer’s disease (AD). As a plant extract, it is found that DL-3-n-butylphthalide (L-NBP) rescues abnormal cognitive behaviors in AD animals.

Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
