Pyruvate kinase directly generates GTP in glycolysis, supporting growth and contributing to guanosine toxicity

mBio
Guanosine triphosphate (GTP) is essential for macromolecular biosynthesis, and its intracellular levels are tightly regulated in bacteria. Loss of the alarmone (p)ppGpp disrupts GTP regulation in Bacillus subtilis, causing cell death in the presence of ...

Erythrocyte Inosine triphosphatase activity: A potential biomarker for adverse events during combination antiretroviral therapy for HIV [PDF]

, 2018
The purine analogues tenofovir and abacavir are precursors of potential substrates for the enzyme Inosine 5’-triphosphate pyrophosphohydrolase (ITPase).

Identification of a guanosine triphosphate-binding site on guinea pig liver transglutaminase. Role of GTP and calcium ions in modulating activity.

Journal of Biological Chemistry, 1987
Guanosine 5'-triphosphate (GTP) was found to inhibit guinea pig liver transglutaminase activity as measured by [3H]putrescine incorporation into casein.

Determination of total potentially available nucleosides in bovine milk [PDF]

, 2010
Bovine colostrum and milk samples were collected from two herds over the course of the first month post-partum, pooled for each herd by stage of lactation and total potentially available nucleosides were determined.

Hypoxanthine-guanine phosphoribosyltransferase and inosine 5’-monophosphate dehydrogenase activities in three mammalian species: aquatic (Mirounga angustirostris), semiaquatic (Lontra longicaudis annectens) and terrestrial (Sus scrofa)

Frontiers in Physiology, 2015
Aquatic and semiaquatic mammals have the capacity of breath hold (apnea) diving. Northern elephant seals (Mirounga angustirostris) have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min ...

Tubulin sequence region beta 155-174 is involved in binding exchangeable guanosine triphosphate.

Journal of Biological Chemistry, 1987
Assembly-competent microtubule protein was directly photoaffinity labeled with [alpha-32P]guanosine triphosphate by UV irradiation. The labeled tubulin was digested with trypsin.

Assignments of backbone 1H, 13C and 15N resonances in H-Ras (1–166) complexed with GppNHp at physiological pH [PDF]

, 2012
The small GTPase Ras is an important signaling molecule acting as a molecular switch in eukaryotic cells. Recent findings of global conformational exchange and a putative allosteric binding site in the G domain of Ras opened an avenue to understanding ...

Caenorhabditis elegans RIG-I Homolog Mediates Antiviral RNA Interference Downstream of Dicer-Dependent Biogenesis of Viral Small Interfering RNAs. [PDF]

, 2017
Dicer enzymes process virus-specific double-stranded RNA (dsRNA) into small interfering RNAs (siRNAs) to initiate specific antiviral defense by related RNA interference (RNAi) pathways in plants, insects, nematodes, and mammals.

Evolution of the bacterial nucleosidase PpnN and its relation to the stringent response

Microbial Cell, 2019
In our recent publication (Zhang et al., 2019), we demonstrate an interesting mode of regulation of purine metabolism unique to Proteobacteria. In this microreview, we would like to reflect on the ideas put forward, with special focus on protein domain ...
