Localized discrete and asymmetric dark-bright soliton-like modes as nonlinear dynamics in microtubules

Heliyon
In the present work, we focus on the longitudinal model of microtubules (MTs) proposed by Satarić et al. (1993) [12], and that considers MT cells to have ferroelectric properties (behaviors) due to dipolar oscillations of dimers within MTs, i.e., a ...

Genome-wide analysis of the UDP-glucose dehydrogenase gene family in Arabidopsis, a key enzyme for matrix polysaccharides in cell walls

, 2007
Arabidopsis cell walls contain large amounts of pectins and hemicelluloses, which are predominantly synthesized via the common precursor UDP-glucuronic acid.

Modulation of calcium mobilization by guanosine 5'-O-(2-thiodiphosphate) in Xenopus oocytes

, 1990
We investigated the effect of intracellular loading of the non-hydrolyzable guanosine 5'-diphosphate analogue GDPßS on calcium mobilization by IP3 and on calcium influx in Xenopus oocytes.

Photoelectrochemical bioanalysis of guanosine monophosphate via the use of coupled enzymatic reactions at a CdS/ZnS quantum dot electrode.

, 2015
A photo-electrochemical sensor for the specific detection of guanosine monophosphate (GMP) is demonstrated, based on three enzymes combined in a coupled reaction assay.

Luminescent Vesicular Nanointerface: A Highly Selective and Sensitive “Turn-On” Sensor for Guanosine Triphosphate

, 2016
A novel amphiphilic Tb3+ complex (TbL3+(I)) consisting of a +3 charged head and a hydrophobic alkyl chain has been developed. It spontaneously self-assembles in water and forms stable vesicles at neutral pH.

Non-canonical Gq activation by orexin receptor type 2 and lemborexant observed in microsecond molecular dynamics simulations

Scientific Reports
Orexins are hypothalamic neuropeptides primarily involved in regulating the sleep/wakefulness cycle and circadian rhythm. They bind to the orexin receptor type 1 (OX1) and type 2 (OX2), well-known drug targets in the treatment of sleep disorders, that ...

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 ...
