CDP-1,2-diacyl-sn-glycerol (CDP-diacylglycerol):myo-inositol phosphatidyltransferase (EC 2.7.8.11, phosphatidylinositol synthase) catalyzes the final step in the de novo synthesis of phosphatidylinositol in the endoplasmic reticulum fraction of germinating soybeans (Glycine max L. var Cutler 71). A variety of solubilization agents were examined for their ability to release phosphatidylinositol ...

In recent years, the ability of ionic surfactants such as sodium dodecyl sulfate (SDS) to solubilize the water-insoluble protein Zein in aqueous solution, referred to as the Zein solubilization test, has been investigated to rank the skin irritation potential and protein denaturation potential of surfactants. However, the potential of cationic surfactants towards solubilization of Zein has not ...

We establish a biophysical model for the dynamics of lipid vesicles exposed to surfactants. The solubilization of the lipid membrane due to the insertion of surfactant molecules induces a reduction of membrane surface area at almost constant vesicle volume. This results in a rate-dependent increase of membrane tension and leads to the opening of a micron-sized pore. We show that solubilization ...

During the stepwise solubilization of sarcoplasmic reticulum vesicles with detergents, the following changes in the structural and enzymatic properties of the preparation are observed: 1. The viscosity of the vesicular suspension initially rises. This change is accompanied by the formation of elongated tubules. Subsequently the membranes are completely disintegrated, resulting in a considerable...

Inclusion body refolding processes are poised to play a major role in the production of recombinant proteins. Improving renaturation yields by minimizing aggregation and reducing chemical costs are key to the industrial implementation of these processes. Recent developments include solubilization methods that do not rely on high denaturant concentrations and the use of high hydrostatic pressure...

Footpad adhesion sites pinch off from the rest of the cell surface during EGTA-mediated detachment of normal or virus-transformed murine cells from their tissue culture substrates. In these studies, highly purified trypsin and testicullar hyaluronidase were used to investigate the selective destruction or solubilization of proteins and polysaccharides in this substrate-attached material (SAM). ...

The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...

Micellar-enhanced ultrafiltration (MEUF) was used to remove phenol from simulant aqueous solutions. The effect of groups difference of cationic surfactant on the solubilization of phenol was investigated through orthogonal experiment, namely, surfactants with the same length of hydrocarbon chain but different hydrophilic head group and vice versa. The effects on the solubilization of
