Nucleoside Triphosphate-Nucleoside Diphosphate Transphosphorylase (Nucleoside Diphosphokinase)

Journal of Biological Chemistry, 1964
Abstract Previous physical studies from this laboratory by sedimentation velocity and diffusion and by sedimentation equilibrium (Yue, R. H., Ratliff, R. L., and Kuby, S. A. (1967) Biochemistry 6, 2923–2932) have permitted an assignment of the kinetic molecular weight of the crystalline brewers' yeast nucleoside diphosphokinase, namely 102,000 (±2,000)

Characterisation of multiple substrate-specific (d)ITP/(d)XTPase and modelling of deaminated purine nucleotide metabolism [PDF]

, 2011
To be viable, organisms possess a number of (deoxy)nucleotide phosphohydrolases, which hydrolyze these nucleotides removing them from the active NTP and dNTP pools. Deamination of purine bases can result in accumulation of such nucleotides as ITP, dITP,

Respiratory virus mRNA vaccines: mRNA Design, clinical studies, and future challenges

Animal Models and Experimental Medicine, EarlyView.
Abstract Respiratory infectious diseases frequently erupt on a global scale, with RNA viruses, such as SARS‐CoV‐2, RSV, and influenza viruses, posing challenges to vaccine development due to their high mutation rates. Traditional vaccine development cycles are lengthy and struggle to keep pace with rapidly evolving viruses, whereas messenger RNA (mRNA)

Love Acoustic Wave-Based Devices and Molecularly-Imprinted Polymers as Versatile Sensors for Electronic Nose or Tongue for Cancer Monitoring

Sensors, 2016
Cancer is a leading cause of death worldwide and actual analytical techniques are restrictive in detecting it. Thus, there is still a challenge, as well as a need, for the development of quantitative non-invasive tools for the diagnosis of cancers and ...

Nevirapine versus Efavirenz for patients co-infected with HIV and Tuberculosis: A Randomised Non-Inferiority Trial [PDF]

, 2013
BACKGROUND: In countries with a high incidence of HIV and tuberculosis co-infection, nevirapine and efavirenz are widely used as antiretroviral therapy but both interact with antituberculosis drugs. We aimed to compare efficacy and safety of a nevirapine-

Lipophilic prodrugs of nucleoside triphosphates as biochemical probes and potential antivirals

Nature Communications, 2015
The antiviral activity of nucleoside reverse transcriptase inhibitors is often limited by ineffective phosphorylation. We report on a nucleoside triphosphate (NTP) prodrug approach in which the γ-phosphate of NTPs is bioreversibly modified.

Achieving scalable expansion of therapeutic porcine hepatocytes in vivo through serial transplantation

Animal Models and Experimental Medicine, EarlyView.
This represents the first serial hepatocyte transplantation pig model designed to investigate the massive hepatocyte proliferation in vivo. Leveraging this novel model, we achieved serial hepatocyte transplantation and regeneration in a porcine model, where the transplanted hepatocytes effectively repopulated the livers of two‐generation model pigs in ...

Nucleoside phosphorylation by the mineral schreibersite

Scientific Reports, 2015
Phosphorylation of the nucleosides adenosine and uridine by the simple mixing and mild heating of aqueous solutions of the organic compounds with synthetic analogs of the meteoritic mineral schreibersite, (Fe,Ni)3P under slightly basic conditions (pH ~9)
