A gene encoding a DUF523 domain protein is involved in the conversion of 2-thiouracil into uracil
(Environmental microbiology reports, 2018)Modified nucleotides are present in many RNA species in all Domains of Life. While the biosynthetic pathways of such nucleotides are well studied, much less is known about the degradation of RNAs and the return to the ... -
A quantitative model of thermal stabilization and destabilization of proteins by ligands
(Biophysical Journal, 2008)Equilibrium binding ligands usually increase protein thermal stability by an amount proportional to the concentration and affinity of the ligand. High-throughput screening for the discovery of drug-like compounds uses an ... -
A quick and reliable method for genome-wide host factor screening of Saccharomyces cerevisiae killer toxins
(Biologija, 2016)Numerous yeasts produce toxic compounds to fight the competitors. Such compounds include small molecules (like antibiotics), antibiotic peptides, and also larger proteins, including killer toxins. Their ability to affect ... -
A red-emitting thiophene-modified BODIPY probe for fluorescence lifetime-based polarity imaging of lipid droplets in living cells
(Journal of materials chemistry B, 2023)Intracellular polarity in lipid droplets as well as other organelles may provide useful knowledge about various processes taking place in live cells. Therefore, small fluorophores capable of visualising polarity are ... -
A series of new luminescent non-planar 1,8-naphthyridine derivatives giving coloured and close-to-white electroluminescence spectra
(Journal of luminescence, 2017)We report a synthesis of 37 new 1,8-naphthyridine based compounds having a non-planar bicyclic moiety (bicyclo[3.3.1]nonane, bicyclo[3.3.0]octane and camphor). We measured energetic characteristics (EHOMO=[−5.9; −5.4] eV, ... -
A study on machine learning methods’ application for dye adsorption prediction onto agricultural waste activated carbon
(Nanomaterials: Special issue: Applications of nanomaterials in environmental science, 2021)The adsorption of dyes using 39 adsorbents (16 kinds of agro-wastes) were modeled using random forest (RF), decision tree (DT), and gradient boosting (GB) models based on 350 sets of adsorption experimental data. In addition, ... -
Acute toxic effects caused by the co-exposure of nano/microparticles and hydroxychloroquine in Salmo Trutta at early development
