Tubulin polymerization in dimethyl sulfoxide.

5368 Tubulin Polymerization in Dimethyl Sulfoxide

The self-assembly of tubulin devoid of microtubuleassociated proteins (MAPs) has been studied using a MES buffer containing dimethyl sulfoxide (MezSO). Between 6% and 12% v/v MeZSO, the tubulin forms polymers which resemble microtubules in their morphology and chemical properties. These MezSO microtubules, like normal microtubules, require GTP for assembly and are sensitive to cold, calcium ion...

DFT study of dimers of dimethyl sulfoxide in gas phase

Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...

Diaqua­bis­(dimethyl sulfoxide-κO)­disaccharinatocadmium

The title compound, [Cd(C(7)H(4)NO(3)S)(2)(C(2)H(6)OS)(2)(H(2)O)(2)], contains a Cd(2+) cation in an octahedral coordination environment. The metal atom is surrounded by the two different neutral ligands dimethyl sulfoxide (DMSO) and water, each coordin-ating through the O atom. The anionic saccharinate (sac; 1,1,3-trioxo-2,3-dihydro-1λ(6),2-benzothia-zol-2-ide) ligand coordin-ates through the ...

Clinical Considerations of Dimethyl Sulfoxide

Equilibrium Acidities in Dimethyl Sulfoxide Solution

The first acidity scale to be established in a pure solvent other than water was the result of the pioneering work of Conant, Wheland, and McEwen in ether or ben~ene .~ During the past 20 years an ion-pair acidity scale covering an "effective pKa rangefrom about 15 to 40 has been developed in cyclohexylamine (CHA),6 and similar studies in other low-dielectric-constant solvents including 1,2-dim...
