Polyoxometalates--potent and selective ecto-nucleotidase inhibitors.

Biochem. Pharmacol. 93(2) , 171-81, (2015)

Polyoxometalates (POMs) are inorganic cluster metal complexes that possess versatile biological activities, including antibacterial, anticancer, antidiabetic, and antiviral effects. Their mechanisms of action at the molecular level are largely unknown. Howeve...

The [NiFe]-Hydrogenase of Pyrococcus furiosus Exhibits a New Type of Oxygen Tolerance.

J. Am. Chem. Soc. 137 , 13556-65, (2015)

We report the first direct electrochemical characterization of the impact of oxygen on the hydrogen oxidation activity of an oxygen-tolerant, group 3, soluble [NiFe]-hydrogenase: hydrogenase I from Pyrococcus furiosus (PfSHI), which grows optimally near 100 °...

Low cost referenced luminescent imaging of oxygen and pH with a 2-CCD colour near infrared camera.

Analyst 139(19) , 4924-33, (2014)

A low cost imaging set-up for optical chemical sensors based on NIR-emitting dyes is presented. It is based on a commercially available 2-CCD colour near infrared camera, LEDs and tailor-made optical sensing materials for oxygen and pH. The set-up extends com...

Analysis of phosphate and phosphate containing headgroups enzymatically cleaved from phospholipids of Bacillus subtilis by capillary electrophoresis.

Anal. Bioanal. Chem 407 , 7215-20, (2015)

A new, fast, selective, and reliable capillary electrophoresis method has been developed for analysis of selected phosphoesters (phosphoserine, phosphoethanolamine, phosphoglycerol) and phosphate. The method is based on separation of specific phosphate contai...

mRNA maturation in giant viruses: variation on a theme.

Nucleic Acids Res. 43 , 3776-88, (2015)

Giant viruses from the Mimiviridae family replicate entirely in their host cytoplasm where their genes are transcribed by a viral transcription apparatus. mRNA polyadenylation uniquely occurs at hairpin-forming palindromic sequences terminating viral transcri...

Distinctive Structure of the EphA3/Ephrin-A5 Complex Reveals a Dual Mode of Eph Receptor Interaction for Ephrin-A5.

PLoS ONE 10 , e0127081, (2015)

The Eph receptor tyrosine kinase/ephrin ligand system regulates a wide spectrum of physiological processes, while its dysregulation has been implicated in cancer progression. The human EphA3 receptor is widely upregulated in the tumor microenvironment and is ...

Optical detection of paraoxon using single-walled carbon nanotube films with attached organophosphorus hydrolase-expressed Escherichia coli.

Sensors (Basel.) 15 , 12513-25, (2015)

In whole-cell based biosensors, spectrophotometry is one of the most commonly used methods for detecting organophosphates due to its simplicity and reliability. The sensor performance is directly affected by the cell immobilization method because it determine...

Enhancing the natural folate level in wine using bioengineering and stabilization strategies.

Food Chem. 194 , 26-31, (2015)

Folate deficiency is linked to many diseases, some of which may have higher probability in individuals with alcohol-induced alterations in one-carbon metabolism. Our study shows that folate content in commercial wine is not related to white or red varieties, ...

Determination of 3-mercaptopropionic acid by HPLC: A sensitive method for environmental applications.

J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 992 , 103-8, (2015)

The organic sulfur compound 3-mercaptopropionic acid (3-MPA) is an important thiol intermediate in organic sulfur metabolism in natural environments. It is generated during degradation of sulfur-containing amino acids (e.g. methionine) and from demethylation ...

Mesoporous titania thin films as efficient enzyme carriers for paraoxon determination/detoxification: effects of enzyme binding and pore hierarchy on the biocatalyst activity and reusability.

Analyst 139(12) , 3127-36, (2014)

In this work we demonstrate the efficient immobilization of histidine 6-tagged organophosphate hydrolase (His6-OPH), an organophosphate-degrading enzyme, on mesoporous titania thin films. This permits the use of the biocatalyst films as efficient tools in the...
