Development of a quinoxaline-based fluorescent probe for quantitative estimation of protein binding site polarity.

چکیده
The compound 2-[(1E)-2-(1H-pyrrol-2-yl)ethenyl]-quinoxaline (PQX) is a promising fluorescent chromophore for the estimation of protein binding site polarity, due to its full-color solvatochromic fluorescence. A linear relationship was obtained between the peak emission wavenumber and E(T)(N) (normalized solvent polarity). The BSA binding site polarity was estimated from the solvatochromic plot.

Evaluation and Characterization of Free and Immobilized Acethylcholinesterase with Fluorescent Probe, Differential Scanning Calorimetry and Docking
Acetylcholinesterase (AChE) enzyme which catalyses the hydrolysis of choline esters, such as acetylcholine, is very important in nerve function. Previous structural studies showed the possible amyloid fibril formation on the AChE. Therefore it is important to understand interaction of ligands to prevent the formation of amyloid fibrils. The purpose of the present study was to char...
متن کاملFemtosecond studies of protein-DNA binding and dynamics: histone I.
In this contribution, we report studies of the nature of binding interactions and dynamics of protein histone I (H1) with ligands in solution and as a complex with DNA, an important biological process for the higher-order structure in chromatin. With femtosecond time resolution, we examined the role of solvation by water, the micropolarity at the interface of the binding site(s) of H1, and the ...

It is possible to use transgenic plants, as bioreactors, for the production of recombinant inexpensive chemicals and drug components. Transient gene expression is an appropriate alternative to stable transformation because it allows an inexpensive and rapid method for expression of recombinant proteins in plant tissues. In recent years, plant viral vectors have been increasingly developed as su...

Angiogenesis is the generation of new blood vessels from the existing vasculature. The angiogenic programme requires the degradation of the basement membrane, endothelial cell migration and invasion of the extracellular matrix, with endothelial cell proliferation and capillary lumen formation before maturation and stabilization of the new vasculature. Angiogenesis is dependent on a delicate equ...
