physiological function
-
GLS2 identified as a previously uncharacterized p53 target gene to regulate cellular energy metabolism and antioxidant defense. GLS regulates cellular energy metabolism by increasing production of glutamate and 2-oxoglutarate, which in turn results in enhanced mitochondrial respiration and ATP generation. Furthemore GLS2 regulates antioxidant defense function in cells by increasing reduced glutathione levels and decreasing reactive oxygen spcies (ROS) levels, which in turn protects cells from oxidative stress
physiological function
-
GLS2 probably controls the intracellular reactive oxygen species (ROS) and the apoptotic response fascilitating the ability of p53 to protect cells from accumulation of genomic damage and allows cells to survive after mild and repairable genotoxic stress
physiological function
-
glutaminase C is important for tumor metabolism. Glutamate production by mitochondrial glutaminase C, the first enzyme in glutaminolysis, is a key process for body homeostasis, and a crucial carbon donor for amino acid and lipid synthesis in tumor cells
physiological function
-
kidney-type glutaminase activity in cells is stimulated by EGF, and kidney-type glutaminase associates with all three kinase components of the Raf-1/Mek2/Erk signaling module, interaction mode, the bound ligand makes several hydrogen-bonding contacts to Gln285, Ser286, Asn335, Glu381, Asn388, Tyr414, Tyr466, and Val484, overview. The kidney-type glutaminase active and inhibitory sites show a dynamic nature, cross-talk and regulation of kidney-type glutaminase activities by EGF-mediated Raf-Mek-Erk signaling. The enhanced activity is abrogated by kinase-dead, dominant negative mutants of Raf-1 (Raf-1-K375M) andMek2 (Mek2-K101A), protein phosphatase PP2A, and Mek-inhibitor U0126, indicative of phosphorylation-dependent regulation. kidney-type glutaminase can interact equally well with the wild-type or mutant forms of Raf-1 and Mek2. The activity of kidney-type glutaminase is directly regulated by Raf-Mek-Erk downstream of EGF receptor
physiological function
glutaminase functions in cellular metabolism of every organism by supplying nitrogen required for the biosynthesis of a variety of metabolic intermediates, while glutamic acid plays a role in both sensory and nutritional properties of food

neurotransmitter glutamate has been thought to derive mainly from glutamine via the action of glutaminase type 1, the GLS1 pathway is essential for maintaining the function of active synapses, knockout mice lacking brain/kidney phosphate-activated glutaminase have impaired glutamatergic synaptic transmission, altered breathing, disorganized goal-directed behavior and die shortly after birth

structure-based phosphate activation mechanism of GAC and GLS1/KGA, introducing the tetramerization-induced lifting of a gating loop essential for the phosphate-dependent activation process, overview. Phosphate binds inside the catalytic pocket rather than at the oligomerization interface. Phosphate also mediates substrate entry by competing with glutamate. GLS1/KGA is as effective as GLS2/LGA, but presents an eightfold gain in efficiency at 50 mM phosphate, with kcat-app/Km-app of 0.4 mM/s and 17.6 mM/s, respectively.
