Superfolder variant of the green fluorescent protein (sfGFP) became a favorite probe for examination of the unfolding-refolding processes of fluorescent proteins with beta-barrel structure owing to its reversible unfolding in comparison with other fluorescent proteins. Its benefit is the proper folding even in fusion constructions with poorly folded polypeptides. We noticed that guanidine thioc...

Several hypotheses to elucidate the linkage isomer preference of the thiocyanate (SCN(-)) ion have been offered. For complexes with small coordination numbers (i.e., 1 and 2) and groups 11 (Cu-triad) and 12 (Zn-triad) metals, different levels of theory and a variety of basis sets have been employed to study linkage isomerism. Similar results are obtained for all density functionals tested, pure...

10.1016/S1674-6384(15)60065-X Objective To study the pharmacokinetic properties of Fufang Baijiezi Gel (FBG) after different acupoints administration. Methods Sinapine thiocyanate, tetrahydropalmatine, 6-gingerol, and asarinin, which were four substances of FBG, were determined by a sensitive liquid chromatography tandem mass spectrometry method (LC-MS) both in plasma and dermal microdialysates...

Oblivious to ion specificity, pH has been a key parameter for macromolecular solutions for little more than a century. We here widen the concept by describing the ionization of macromolecules not only via pH, but also pX where X are other binding species. Using binding constants, measured by NMR, of chloride and thiocyanate to amino acid motifs on y-crystallin, we calculate i) titration curves ...

The visible spectra of sperm-whale metmyoglobin and its fluoride, hydroxide, cyanide, azide, cyanate, formate, acetate, thiocyanate and nitrite derivatives were measured and resolved into Gaussian components. A linear correlation between the intensity of the band at 18500cm.(-1) and the magnetic susceptibility is found, suggesting that the band is the beta-band of the low-spin form. The analyse...

An investigation was undertaken to study the factors which cause grossly elevated values in an automated procedure for chloride when the sample is contaminated with bromide. The questioned mercuric thiocyanate method of the autoanalyzer was compared to a similar system utilizing mercuric 2, 4, 6-tripyridyl-s-triazine as a substitute ligand source in the chloride exchange system. It was determin...

In this study, a zinc plant purification cake (CINKUR Co. Turkey) was leached with sulphuric acid and an acidic leach solution containing Zn(II), Fe(II), Pb(II), Al(III), Cu(II), Co(II) and Ni(II) ions was obtained. After purification, ammonium thiocyanate and water were added to the remaining leach solution containing Co(II) and Ni(II) ions to adjust the chemical media and ion concentration. T...

Fasicularin is a structurally novel thiocyanate-containing alkaloid isolated from the ascidian Nephteis fasicularis. Early biological experiments suggested that this compound's cytotoxic properties may stem from its ability to damage cellular DNA. Sequence gel analysis reveals that treatment of a 5'-32P-labeled DNA duplex with fasicularin in pH 7.0 buffer causes strand cleavage selectively at g...
