Preparation and characterization of antifouling poly(vinyl chloride-co-poly(ethylene glycol)methyl ether methacrylate) membranes(Link)

Journal of Membrane Science

Two series of antifouling microfiltration membranes (MF) with different pure water permeabilities were fabricated using poly(vinyl chloride-co-poly(ethylene glycol)methyl ether methacrylate) (poly(VC-co-PEGMA)) copolymers with different PEGMA segment percentage via nonsolvent-induced phase separation (NIPS) method. For each series of the prepared membranes, the initial pure water permeability was...more


Interaction of arginine, lysine, and guanidine with surface residues of lysozyme: implication to protein stability(Link)

Journal of Biomolecular Structure and Dynamics
March 2, 2015
Additives are widely used to suppress aggregation of therapeutic proteins. However, the molecular mechanisms of effect of additives to stabilize proteins are still unclear. To understand this, we herein perform molecular dynamics simulations of lysozyme in the presence of three commonly used additives: arginine, lysine, and guanidine. These additives have different effects on stability of proteins...more


Effects of Water Concentration on the Free Volume of Amino Acid Ionic Liquids Investigated by Molecular Dynamics Simulations(Link)

The Journal of Physical Chemistry B
December 15, 2014
Amino acid ionic liquids (AAILs) are gaining attention because of their potential in CO2 capture technology. Molecular dynamics simulations of AAILs tetramethylammonium glycinate ([N1111][Gly]), tetrabutylammonium glycinate ([N4444][Gly]), and 1,1,1-trimethylhydrazinium glycinate ([aN111][Gly]) and their corresponding mixtures with water were performed to investigate the effect of water...more


A Saccharomyces cerevisiae Assay System to Investigate Ligand/AdipoR1 Interactions That Lead to Cellular Signaling(Link)

PLOS ONE
June 7, 2013
Adiponectin is a mammalian hormone that exerts anti-diabetic, anti-cancer and cardioprotective effects through interaction with its major ubiquitously expressed plasma membrane localized receptors, AdipoR1 and AdipoR2. Here, we report a Saccharomyces cerevisiae based method for investigating agonist-AdipoR interactions that is amenable for high-throughput scale-up and can be used to study both...more


Molecular mechanism of ATP hydrolysis in F1-ATPase revealed by molecular simulations and single-molecule observations(Link)

Journal of the American Chemical Society
May 11, 2012
Enzymatic hydrolysis of nucleotide triphosphate (NTP) plays a pivotal role in protein functions. In spite of its biological significance, however, the chemistry of the hydrolysis catalysis remains obscure because of the complex nature of the reaction. Here we report a study of the molecular mechanism of hydrolysis of adenosine triphosphate (ATP) in F1-ATPase, an ATP-driven rotary motor protein....more


Dynamic and structural changes in the minimally restructuring EcoRI bound to a minimally mutated DNA chain(Link)

Journal of Biomolecular Structure and Dynamics
February 1, 2012
The dynamics of a protein plays an important role in protein functionality. Here, we examine the differences in the dynamics of a minimally restructuring protein, EcoRI, when it is bound to its cognate DNA and to a noncognate sequence which differs by just a single basepair. Molecular dynamics simulations of the complexes and essential dynamics analyses reveal that the overall dynamics of the...more


Arginine–aromatic interactions and their effects on arginine‐induced solubilization of aromatic solutes and suppression of protein aggregation(Link)

Biotechnology progress
January 1, 2012
We examine the interaction of aromatic residues of proteins with arginine, an additive commonly used to suppress protein aggregation, using experiments and molecular dynamics simulations. An aromatic-rich peptide, FFYTP (a segment of insulin), and lysozyme and insulin are used as model systems. Mass spectrometry shows that arginine increases the solubility of FFYTP by binding to the peptide, with...more


Effects of arginine on heat‐induced aggregation of concentrated protein solutions(Link)

Biotechnology progress
March 1, 2011
Arginine is one of the commonly used additives to enhance refolding yield of
proteins, to suppress aggregation of proteins, and to increase solubility of proteins, and yet
the molecular interactions that contribute to the role of arginine are unclear. Here, we
present experiments, using bovine serum albumin (BSA), lysozyme (LYZ), and β-
lactoglobulin (BLG) as model proteins, to show that...more
