Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium
By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Cloning, expression, purification, and structural modeling of the Chandipura virus matrix protein
This research protocol offers a guide for the cloning, expression, and purification of the Chandipura virus matrix protein using E. coli. It also includes a step‐by‐step procedure for cloning, expressing, and conducting fluorescence imaging of GFP‐fused Chandipura virus matrix protein in mammalian cell lines.

DNA extraction: High yield is not synonymous with high diversity
The quality, amount, and, in the case of polymicrobial samples, diversity of isolated DNA presupposes the precision of downstream application results. As part of a larger study on colorectal cancer, the aim of this work was to identify the DNA extraction

Chemotherapies such as doxorubicin can have toxic effects on healthy cardiovascular/heart tissue. Following up on a doxorubicin toxicity study in mice without tumors where nitrate water was cardioprotective (lessened toxicity), this study with tumor‐bearing mice undergoing doxorubicin treatment showed no negative effect of nitrate and nitrite on drug ...

Background Bacteria associated with insects can have a substantial impact on the biology and life cycle of their host. The checkerboard DNA-DNA hybridization technique is a semi-quantitative technique that has been previously employed in odontology to ...

Dna Supercoiling and Bacterial Gene Expression [PDF]
DNA in bacterial cells is maintained in a negatively supercoiled state. This contributes to the organization of the bacterial nucleoid and also influences the global gene expression pattern in the cell through modulatory effects on transcription.
