Cleavage of the apoptosis inhibitor DIAP1 by the apical caspase DRONC in both normal and apoptotic drosophila cells [PDF]

open access: yes, 2005
In Drosophila S2 cells, the apical caspase DRONC undergoes a low level of spontaneous autoprocessing. Unintended apoptosis is prevented by the inhibitor of apoptosis DIAP1, which targets the processed form of DRONC for degradation through its E3 ...

Glucocorticoid-Inducible Glutamine Synthetase in GH Cells of Chick Embryos, Gallus domesticus: Ontogeny of Glutamine Synthetase, GH, and Pit-1 Protein in the Pituitary Gland

open access: yesThe Journal of Poultry Science, 2006
It has been known that glutamine synthetase (GS, L-glutamate ammonia ligase) is an enzyme that catalyzes ATP-dependent condensation of glutamate and ammonia to form glutamine, and that GS and growth hormone (GH) are proteins that are induced by ...

The glutaminase-dependent acid resistance system. Qualitative and quantitative assays and analysis of its distribution in enteric bacteria [PDF]

open access: yes, 2018
Neutralophilic bacteria have developed several strategies to overcome the deleterious effects of acid stress. In particular, the amino acid-dependent systems are widespread, with their activities overlapping, covering a rather large pH range, from 6 to

TP53-inducible Glycolysis and Apoptosis Regulator (TIGAR) Metabolically Reprograms Carcinoma and Stromal Cells in Breast Cancer. [PDF]

open access: yes, 2016
A subgroup of breast cancers has several metabolic compartments. The mechanisms by which metabolic compartmentalization develop in tumors are poorly characterized. TP53 inducible glycolysis and apoptosis regulator (TIGAR) is a bisphosphatase that reduces

Alternative cell death pathways and cell metabolism [PDF]

open access: yes, 2013
While necroptosis has for long been viewed as an accidental mode of cell death triggered by physical or chemical damage, it has become clear over the last years that necroptosis can also represent a programmed form of cell death in mammalian cells.

Glutamine synthetase evolutionary history revisited: Tracing back beyond the Last Universal Common Ancestor

open access: yesEvolution; international journal of organic evolution, 2022
Glutamine synthetase (GS; EC 6.3.1.2, L‐glutamate: ammonia ligase) is an essential enzyme in nitrogen assimilation. It catalyzes glutamine synthesis using glutamate and ammonium with ATP hydrolysis.
