A Novel Salt-Tolerant L-Glutaminase: Efficient Functional Expression, Computer-Aided Design, and Application

Fermentation, 2022
The low productivity in long fermentation duration and high-salt working conditions limit the application of L-glutaminase in soy sauce brewing. In this study, a novel L-glutaminase (LreuglsA) with eminent salt tolerance was mined and achieved more than ...

Kinetic properties of Streptomyces canarius L- Glutaminase and its anticancer efficiency [PDF]

Brazilian Journal of Microbiology, 2015
L-glutaminase was produced by Streptomyces canarius FR (KC460654) with an apparent molecular mass of 44 kDa. It has 17.9 purification fold with a final specific activity 132.2 U/mg proteins and 28% yield recovery. The purified L-glutaminase showed a maximal activity against L-glutamine when incubated at pH 8.0 at 40 °C for 30 min.

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

Advanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Improving the Production of Salt-Tolerant Glutaminase by Integrating Multiple Copies of Mglu into the Protease and 16S rDNA Genes of Bacillus subtilis 168

Molecules, 2019
In this study, the Micrococcus luteus K-3 glutaminase was successfully over-expressed in the GRAS (Generally Recognized as Safe) Bacillus subtilis strain 168 by integration of the Mglu gene in the 16S rDNA locus. This was done in order to screen a strain

YTHDC1 Orchestrates Glucose and Glutamate Rewiring to Overcome Lethal Metabolic Stress in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Lai et al. find that m6A reader YTHDC1 is specifically overexpressed in triple‐negative breast cancer (TNBC) and orchestrates glucose and glutamine metabolism in an m6A‐dependent manner to confer robust adaptability to lethal metabolic stress. Leveraging YTHDC1 knockdown‐induced metabolic vulnerability, an ATF4 mRNA‐targeted nanotherapy is developed to

Reversing Macrophage Immunometabolic Dysfunction in Prolonged Infections Via a Glutaminolysis‐Fueled Restoration‐Based Hierarchically Selective Therapeutic System

Advanced Science, EarlyView.
A hierarchically selective immunotherapeutic nanoplatform, mGls@HEV‐MTP, selectively restores macrophage immunocompetence through GLS1‐mediated restoration of glutaminolysis‐fueled anaplerosis. Concurrently, it renders Staphylococcus aureus (S. aureus) more readily recognizable to the metabolically reprogrammed macrophages, thereby facilitating ...

DLST Succinylation‐Mediated Mitochondrial Metabolic Remodeling and Cuproptosis Resistance Promote Malignant Progression of Lung Adenocarcinoma

Advanced Science, EarlyView.
The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.
