Surface charge fine tuning of reversed-phase/weak anion-exchange type mixed-mode stationary phases for milder elution conditions.

J. Chromatogr. A. 1409 , 189-200, (2015)

A series of new mixed-mode reversed-phase/weak anion-exchange (RP/WAX) phases have been synthesized by immobilization of N-undecenyl-3-α-aminotropane onto thiol-modified silica gel by thiol-ene click chemistry and subsequent introduction of acidic thiol-endca...

The effect of enzymatic reaction on dissolution rate: theoretical analysis and experimental test.

J. Pharm. Sci. 75(2) , 195-203, (1986)

The dissolution behavior of N-acetylphenylalanine ethyl ester (1) and N-benzoyltyrosine ethyl ester (2) from a rotating disk into aqueous solutions containing the enzyme alpha-chymotrypsin was investigated. The effect of the bulk enzymatic reaction on the dis...

Immobilization of enzymes on fumed silica nanoparticles for applications in nonaqueous media.

Methods Mol. Biol. 743 , 147-160, (2011)

Enzymatic catalysis in nonaqueous media is considered as an attractive tool for the preparation of a variety of organic compounds of commercial interest. This approach is advantageous for numerous reasons including the enhanced stability of some substrates an...

Protease activation in glycerol-based deep eutectic solvents.

J. Mol. Catal., B Enzym. 72 , 163-167, (2011)

Deep eutectic solvents (DESs) consisting of mixtures of a choline salt (chloride or acetate form) and glycerol are prepared as easily accessible, biodegradable, and inexpensive alternatives to conventional aprotic cation-anion paired ionic liquids. These DES ...

Purification and characterization of organic solvent stable protease from Bacillus licheniformis RSP-09-37.

Appl. Microbiol. Biotechnol. 79 , 399-405, (2008)

A protease was purified from the cell-free supernatant of Bacillus licheniformis RSP-09-37, a mutant from a thermophilic bacterial strain, B. licheniformis RSP-09, using affinity chromatography with alpha-casein agarose resin. The protease was purified 85-fol...

High transesterification activities of immobilized proteases in new ether-functionalized ionic liquids.

Biotechnol. Lett. 32 , 1109-1116, (2010)

Three new ether-functionalized hydrophobic ionic liquids (ILs) were synthesized. Two proteases (subtilisin and alpha-chymotrypsin both covalently immobilized on chitosan) exhibited high synthetic activity (1-3 micromol/min x g) and selectivity (>97-99%, ester...

Investigations into the thermodynamics of polypeptide interaction with nonpolar ligands.

Anal. Chem. 71(21) , 4874-85, (1999)

In this paper, we describe a general procedure to evaluate the thermodynamics of the interaction between polypeptides and hydrophobic ligands in the presence of aquo-organic solvent mixtures. These studies address experimental requirements for the determinati...

Alpha-chymotrypsin catalysis in imidazolium-based ionic liquids.

Biotechnol. Bioeng. 75(2) , 181-6, (2001)

The transesterification reaction of N-acetyl-L-phenylalanine ethyl ester with 1-propanol catalyzed by alpha-chymotrypsin was examined in the ionic liquids 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF(6)]) and 1-octyl-3-methylimidazolium hexafluo...

Studies on the mechanism of NK cell lysis.

J. Immunol. 128(4) , 1786-91, (1982)

The mechanism of cytolysis by murine NK cells was analyzed using a variety of metabolic inhibitors that have proven informative in studying the lytic mechanism of CTL and the mechanism of histamine release by mast cells. Target cell binding occurred in the ab...

Quantitation of aromatic residues in proteins: model compounds for second-derivative spectroscopy.

Biochemistry 21(11) , 2600-6, (1982)

The ultraviolet absorption spectrum of proteins in 6 M guanidine is approximately that of the sum of the spectra of the constituent aromatic amino acids, phenylalanine, tyrosine, and tryptophan, plus contributions from light scattering and disulfides. A multi...
