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

open access: yesFrontiers 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 ...

What are guanosine triphosphate-binding proteins doing in mitochondria?

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1998
The discovery of GTP-binding proteins in mitochondria is a recent event. These regulatory proteins may be participating in membrane fusion and thereby playing important roles in the physiology of the mitochondrion. So far, it has been proposed that GTP-binding protein mediated membrane fusion may be involved in protein import, steroid hormone ...

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

open access: yes, 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 ...

Inherited abnormalities in platelet organelles and platelet formation and associated altered expression of low molecular weight guanosine triphosphate-binding proteins in the mouse pigment mutant gunmetal.

open access: yesBlood, 1993
Gunmetal (gm/gm) is a recessively inherited mouse pigment dilution mutant that has high mortality and poor reproductive rates. In these studies, several hematologic defects were found associated with the mutation, including prolonged bleeding times ...

Nonequilibrium Self‐Assembly of Microtubules Through Stepwise Sequential Interactions of DNA

open access: yesSmall, EarlyView.
This study presents a molecular swarm system activated through stepwise DNA interactions. DNA‐tethered microtubules exchange signals via specific sequence recognition, enabling sequential assembly and communication. This innovative approach advances autonomous molecular machine development, offering potential for adaptive, active, and complex ...

Development of Dipicolylamine-Modified Cyclodextrins for the Design of Selective Guest-Responsive Receptors for ATP

open access: yesMolecules, 2018
The construction of supramolecular recognition systems based on specific host–guest interactions has been studied in order to design selective chemical sensors. In this study, guest-responsive receptors for ATP have been designed with cyclodextrins (CyDs)

Clinical Evaluation of Potential Interaction Between Bemnifosbuvir and Ruzasvir With an Assessment of Food Effect: Results of a Phase 1 Study in Healthy Participants. [PDF]

open access: yesClin Pharmacol Drug Dev
Abstract A combination of nucleotide hepatitis C virus (HCV) nonstructural protein (NS) 5B and 5A inhibitors is a preferred standard of care for treating chronic HCV. Bemnifosbuvir is a novel oral guanosine nucleotide prodrug with potent pan‐genotypic inhibitory activity against HCV NS5B.

Specific ATP Detection Using Molecule‐Responsive DNA Nanopores

open access: yesSmall, EarlyView.
A molecule‐responsive DNA nanopore that provides open/close states by the interaction between an aptamer and analytes is rationally designed. This paper shows the applicability of DNA nanopores for stochastic nanopore sensing by revealing analyte‐concentration dependency, voltage‐dependency, and open/close mechanism.

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

open access: yesMicrobial 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 ...
