An Alternative Enzyme Based Method for Synthesis of Alkyl-Glycosides Mohd Younis Rather1 and Saroj Mishra2*
Rather and Mishra Sustainable Chemical Processes 2013, 1:7 http://www.sustainablechemicalprocesses.com/content/1/1/7 REVIEW Open Access β-Glycosidases: An alternative enzyme based method for synthesis of alkyl-glycosides Mohd Younis Rather1 and Saroj Mishra2* Abstract Alkyl-glycosides and -polyglycosides are environment friendly, non-ionic surfactants with favourable properties like biodegradability and chemical stability. These are extensively used in personal care products, pharmaceutical preparations and membrane protein research. Commercial production of these surfactants is carried out in multiple steps through Fischer glycosylation reactions under extreme conditions in the presence of toxic catalysts. β-glycosidases provide an alternative enzymatic method for their synthesis as these are easily available from microbial systems and exhibit broad substrate specificity and high stereo-selectivity. This review highlights the recent progress in glycosidase catalyzed synthesis of alkyl-glycosides. Several reaction parameters that affect the overall reaction kinetics, such as, water activity, nature of the glycosyl donor, pH of the reaction medium, reaction time, temperature and source of enzyme are discussed. Strategies available to enhance the yield, including two-phase solvent systems and immobilization are described. Current challenges and future prospects in the biological routes of synthesis are also reviewed.

In this review I provide an overview of different useful approaches to study these Mixed micelle complexes and identify eight different issues which define central concepts in the field.

Biochem. 226, 1029-1038 (1994) provided by Digital.CSIC 0 FEBS 1994 Structural phase transitions involved in the interaction of phospholipid bilayers with octyl glucoside Alfonso DE LA MAZA and Jose Luis PARRA Departamento de Tensioactivos, Centro de Investigacibn y Desarrollo (C. I. D. ), Consejo Superior de Investigaciones Cientificas (C. S. 1. C.), Barcelona, Spain (Received September 26, 1994) - EJB 94 1462/6 The transitional stages induced by the interaction of the nonionic surfactant octyl glucoside (OcOse) on phosphatidylcholine liposomes were studied by means of transmission electron micro- scopy (TEM), light scattering and permeability changes. A linear correlation was observed between the effective surfactantnipid molar ratio (Re; three-stage model proposed for liposome solubiliza- tion) and the OcOse concentration in the initial and final interaction stages, despite showing almost a constant value during bilayer saturation. The bilayer/aqueous phase partition coefficient (K) de- creased in the subsolubilizing interaction steps and increased during solubilization. Thus, whereas a preferential distribution of surfactant monomers in the aqueous phase with respect to the lipid bilayers took place in the initial interaction steps, a larger association of OcOse molecules with these lipids in bilayers occured during solubilization. The initial steps of bilayer saturation (50- 70% permeability) were attained for a lower free surfactant (S,) than that for its critical micellar concentration (cmc). When S, reached the OcOse cmc, solubilization started to occur (Rebat).Large unilamellar vesicles began to form as the OcOse exceeded 60 moVlOO mol, exhibiting for 65 mol/ 100 mol (50% permeability) vesicles of approximately 400 nm. -

Solubilization of lipid bilayers by myristyl sucrose ester: effect of cholesterol and phospholipid head group size C. Toro1, S. A. Sanchez2, A. Zanocco1, E. Lemp1, E. Gratton2, and G. Gunther1 1Laboratorio de Cinética y Fotoquímica, Facultad de Ciencias Químicas y Farmacéuticas, Universidad de Chile, Santiago, Chile 2Laboratory for Fluorescence Dynamics, University of California at Irvine, CA, USA Abstract The solubilization of biological membranes by detergents has been used as a major method for the isolation and purification of membrane proteins and other constituents. Considerable interest in this field has resulted from the finding that different components can be solubilized selectively. Certain membrane constituents are incorporated into small micelles, whereas others remain in the so-called detergent-resistant membrane domains that are large enough to be separated by centrifugation. The detergent resistant fractions contain an elevated percentage of cholesterol, and thus its interaction with specific lipids and proteins may be key for membrane organization and regulation of cellular signaling events. This report focuses on the solubilization process induced by the sucrose monoester of myristic acid, β-D-Fructofuranosyl-6-O-myristyl-α-D-glucopyranoside (MMS), a nonionic detergent. We studied the effect of the head group and the cholesterol content on the process. 1-Palmitoyl-2-oleoyl-sn- glycero-3-phosphocholine (POPC) and Dioctadecyl dimethylammonium chloride (DODAC) vesicles were used, and the solubilization process was followed using Laurdan (6-Dodecanoyl-2- dimethylaminonaphthalene) Generalized Polarization (GP) measurements, carried out in the cuvette and in the 2-photon microscope. -
