A direct electron transfer formaldehyde dehydrogenase biosensor for the determination of formaldehyde in river water
(Talanta, 2021)In this work, we report the construction of a direct electron transfer (DET) biosensor based on NAD-dependent formaldehyde dehydrogenase from Pseudomonas sp. (FDH) immobilized on the gold nanoparticle-modified gold electrode. ... -
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 minimal model of haemoglobin oxygenation kinetics
(Biologija, 2004)A mathematical model based on the current understanding of cooperativity in oxygen binding to haemoglobin and relating the saturation curve of haemoglobin oxygenation to dissociation constants characterizing the affinities ... -
A novel Saccharomyces cerevisiae killer strain secreting the X factor related to killer activity and inhibition of S. cerevisiae K1, K2 and K28 killer toxins
(Indian journal of microbiology, 2016)It was determined that Kx strains secrete an X factor which can inhibit all known Saccharomyces cerevisiae killer toxins (K1, K2, K28) and some toxins of other yeast species—the phenomenon not yet described in the scientific ... -
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 refinement of clinical tumor marker monitoring: Why not use an inverse value of doubling time?
(Medical principles and practice : international journal of the Kuwait University, Health Science Centre, 2021)OBJECTIVES: The aim of this study was to compare prostate-specific antigen (PSA) kinetics - half-life time (HT), doubling time (DT), and elimination rate PSA (ePSA) in prostate cancer (PCa) monitoring. Implementation of ... -
Adaptive response of Saccharomyces hosts to Totiviridae L-A dsRNA viruses Is achieved through intrinsically balanced action of targeted transcription factors
(Journal of fungi, 2022)Totiviridae L-A virus is a widespread yeast dsRNA virus. The persistence of the L-A virus alone appears to be symptomless, but the concomitant presence of a satellite M virus provides a killer trait for the host cell. The ... -
Alcohol oxidase from the yeast Pichia pastoris – a potential catalyst for organic synthesis
(Journal of molecular catalysis B : Enzymatic, 2003)Alcohol oxidase (AO) from the methylotropic yeast Pichia pastoris was isolated and investigated. Wide substrate specificity is characteristic for this enzyme. Unbranched primary alcohols are effectively oxidized by AO to ... -
Alpha-dystrobrevin and its associated proteins in human promyelocytic leukemia cells induced to apoptosis
(Journal of proteomics, 2012)Dystrobrevin is a dystrophin-related component of the dystrophin-associated protein complex (DAPC). Using alpha-dystrobrevin as indicator, we aimed to elucidate the interaction network of the DAPC with other proteins during ... -
Amperometrinių mikrobiojutiklių masyvo modeliavimas
(Lietuvos matematikos rinkinys, 2004)Straipsnyje pateikiamas amperometrinių mikrobiojutiklių, sudarytų fermento mikroreaktorių masyvo pagrindu, matematinis modelis dvimatėje erdvėje. Modelio pagrindas - difuzijos lygtys su netiesiniu nariu, aprašančiu fermento ... -
An experimental and theoretical study of Coprinus cinereus peroxidase-catalyzed biodegradation of isoelectronic to dioxin recalcitrants
(Journal of molecular catalysis B : Enzymatic, 2007)Isoelectronic to dibenzo-p-dioxin (DBD) compounds (ID) containing nitrogen and/or sulfur atom instead of oxygen atom can be oxidized in the presence of fungal peroxidase. To elucidate the structure/activity relationship ... -
Analysis of mechanical performance and durability of self-healing biological concrete
(Construction and building materials, 2020)Concrete is a building material that withstands environmental actions for centuries. Development of concrete technologies enables building up the lightweight, slender, and aesthetically attractive structures. These building ... -
Antibiotic resistance in patients with liver cirrhosis: Prevalence and current approach to tackle.
(World journal of clinical cases, 2023)Regardless of etiology, complications with bacterial infection in patients with cirrhosis are reported in the range of 25%-46% according to the most recent data. Due to frequent episodes of bacterial infection and repetitive ... -
Antioxidants determination with laccase
(Talanta, 2007)The spectrophotometric method of antioxidants determination using recombinant laccase Polyporus pinsitus (rPpL) and Myceliophthora thermophila (rMtL) was developed. The method includes simultaneous oxidation of the antioxidant ... -
Baltijos jūros pagrindinės ekologinės problemos
(Aplinkos apsauga : Vilniaus technikos universiteto mokslo darbai, Nr. 2, 1994)The increase of the antrophological influence on the environment of the Baltic Sea leads to undisarable consequences. So, the Baltic States participation in pollution research is very important. One must select the right ... -
