Expression of Deinococcus geothermalis Trehalose Synthase Gene in Escherichia coli and Its Enzymatic Properties
PublicationA novel trehalose synthase gene from Deinococcus geothermalis (DSMZ 11300) containing 1,692 bp reading-frame encoding 564 amino acids was amplified using PCR. The gene was ligated into pET30Ek/LIC vector and expressed after isopropyl alfa-D-thiogalactopyranoside induction in Escherichia coli BL21(DE3)pLysS. The recombinant trehalose synthase (DgeoTreS) containing a His6 tag at the C-terminus was purified by metal affinity chromatography...

Modulation of cellular response to anticancer treatment by caffeine:inhibition of cell cycle checkpoints, DNA repair and more
PublicationKofeina i inne metyloksantyny wywołują bardzo różne efekty fizjologiczne w organizmie człowieka. W pracy przedstawiamy, które z tych efektów mogą wpływać na skuteczność terapii przeciwnowotworowych. Kofeina może bezpośrednio wpływać na transport oraz aktywację metaboliczną cząsteczek leków do komórki, poprzez tworzenie kompleksów z lekami zawierającymi układy poliaromatyczne. Kofeina hamuje aktywność kinaz ATM/ATR co prowadzi do...

Quest for the Molecular Basis of Improved Selective Toxicity of All-Trans Isomers of Aromatic Heptaene Macrolide Antifungal Antibiotics
PublicationThree aromatic heptaene macrolide antifungal antibiotics, Candicidin D, Partricin A (Gedamycin) and Partricin B (Vacidin) were subjected to controlled cis-trans to all trans photochemical isomerization. The obtained all-trans isomers demonstrated substantially improved in vitro selective toxicity in the Candida albicans cells: human erythrocytes model. This effect was mainly due to the diminished hemotoxicity. The molecular modeling...

The Antimicrobial Potential of Bacteria Isolated from Honey Samples Produced in the Apiaries Located in Pomeranian Voivodeship in Northern Poland
PublicationThe principal objective of this study was to determine whether the honeys produced in apiaries located in Pomeranian Voivodeship (Northern Poland) contain bacteria producing metabolites with growth inhibition potential against important human and animal pathogens. The pathogens included Staphylococcus aurues, Staphyloccocus epidermidis, Escherichia coli, Listeria monocytogenes, Pseudomonas aeruginosa, and Candida albicans. From...

Structural changes of bacterial cellulose due to incubation in conditions simulating human plasma in the presence of selected pathogens
PublicationBacterial nanocellulose (BNC) is a natural biomaterial with a wide range of medical applications. However, it cannot be used as a biological implant of the circulatory system without checking whether it is biodegradable under human plasma conditions. This work aimed to investigate the BNC biodegradation by selected pathogens under conditions simulating human plasma. The BNC was incubated in simulated biological fluids with or...

Enzymes of UDP-GlcNAc biosynthesis in yeast
PublicationD-glukozamina stanowi ważny składnik budulcowy głównych elementów strukturalnych grzybowej ściany komórkowej: chityny, chitozanu i mannoprotein. Inne aminocukry, takie jak D-mannozamina i D-galaktozamina, stosunkowo powszechne w komórkach wyższych organizmów eukariotycznych, rzadko występują u grzybów i są praktycznie nieobecne w komórkach drożdży i drożdżaków. Zawierający glukozaminę nukleotyd cukrowy UDP-GlcNAc jest syntezowany...

Izolacja i identyfikacja psychrotolerancyjnych szczepów drożdży z torfowiska Rucianka zdolnych do efektywnej biodegradacji fenolu w obecności tlenu oraz identyfikacja szlaku metabolicznego zaangażowanego w tym procesie w celu oceny potencjału biotechnologicznego badanych szczepów drożdży
PublicationFenole to grupa toksycznych węglowodorów aromatycznych, a do głównych źródeł ich emisji do środowiska można zaliczyć przemysł chemiczny, procesy przeróbki węgla kamiennego i przemysł tekstylny. Pośród nich, fenol stanowi główne zanieczyszczenie gleb i wód spowodowane związkami fenolowymi. W wyniku realizacji badań prowadzonych w ramach mojej rozprawy doktorskiej wykazałam, że torfowiska mogą stanowić miejsce izolacji mikroorganizmów...

Molecular modelling of transition state analogue inhibitors of glucosamine-6-P synthase and glucose-6-P isomerase.
PublicationStruktura kompleksu 2-amino-2-deoksy-D-glucitolo-6-P (ADGP) z centrum aktywnym syntazy GlcN-6-P z E. coli została wykorzystAna jako punkt wyjścia do modelowania molekularnego analogów ADGP. Używając programu GROMOS96 wygenerowano konformacje analogów o najniższych energiach wewnętrznych, które następnie ''dokowano'' w centrum aktywnym enzymu. Dokonano syntezy wybranych związków i określono parametry kinetyczne i termodynamiczne...

The novel sterilization device: the prototype testing
PublicationCurrently, there are numerous methods that can be used to neutralize pathogens (i.e., devices, tools, or protective clothing), but the sterilizing agent must be selected so that it does not damage or change the properties of the material to which it is applied. Dry sterilization with hydrogen peroxide gas (VHP) in combination with UV-C radiation is well described and effective method of sterilization. This paper presents the design,...
