The enzyme is readily adsorbed front aqueous buffer at room temperature following Langmuir adsorption isotherms in unexpectedly large amounts (25% w/w). Relative hydrophobicity of the copolymers has been assessed by studying adsorption of naphthalene and Fmoc-methionine by the series of copolymers from aqueous solutions. Polymer hydrophobicity appears to increase linearly oil increasing cross-link density from 0.05 to 0.25. Further increase in cross-link density Causes a decrease in naphthalene binding but has little effect on binding of Fmoc-Met. Binding of alpha-chymotrypsin to these copolymers follow the trend for Fmoc-methionine binding, rather than naphthalene binding, indicating involvement of polar interactions along with hydrophobic interactions during binding of protein to the polymer. The adsorbed enzyme undergoes extensive denaturation (ca. 80%) with loss of both tertiary and secondary structure on contact with the copolymers as revealed by fluorescence, CID and Raman spectra of the adsorbed protein. Comparison of enzyme adsorption behavior with Eupergit C, macroporous Amberlite XAD-2, and XAD-7 Suggests that polar interactions of the EGDM ester functional groups with the protein play a significant role in enzyme denaturation.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">4.268</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>25</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Dwivedi, Mayank</style></author><author><style face="normal" font="default" size="100%">Rao, Locanindi Hari Sarvothama</style></author><author><style face="normal" font="default" size="100%">Reddy, Krishna Mohan Srinivasulu</style></author><author><style face="normal" font="default" size="100%">Dhanasekharan, Janakiraman</style></author><author><style face="normal" font="default" size="100%">Rao, Bevara Madhusudana</style></author><author><style face="normal" font="default" size="100%">Kumar, Sriperambudur Rajesh</style></author><author><style face="normal" font="default" size="100%">Ponrathnam, Surendra</style></author><author><style face="normal" font="default" size="100%">Rajan, Chelanattukizhakkemadath Raman</style></author><author><style face="normal" font="default" size="100%">Deokar, Sarika Babasaheb</style></author><author><style face="normal" font="default" size="100%">Mulani, Khudbudin Baban</style></author><author><style face="normal" font="default" size="100%">Ghorpade, Ravindra V.</style></author><author><style face="normal" font="default" size="100%">Bhongale, Sunil Sitaram</style></author><author><style face="normal" font="default" size="100%">Nalawade, Archana Chetan</style></author><author><style face="normal" font="default" size="100%">Sontakke, Kalpana Vishwanathrao</style></author><author><style face="normal" font="default" size="100%">Shaikh, Wasif Abdul Lateef</style></author><author><style face="normal" font="default" size="100%">Chavan, Nayaku</style></author><author><style face="normal" font="default" size="100%">Qureshi, Mohammed Shadbar</style></author><author><style face="normal" font="default" size="100%">Dhoble, Deepa Arun</style></author><author><style face="normal" font="default" size="100%">Mule, Smita Atmaram</style></author><author><style face="normal" font="default" size="100%">Bhosle, Sonali Madhavrao</style></author><author><style face="normal" font="default" size="100%">Momin, Mohasin Shamshuddin</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Amino functionalized oligoimides telechelics</style></title></titles><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">AUG</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">2922/DEL/2010 A</style></number><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;This invention relates to a process for the preparation of amino functionalized oligoimide telechelics. More particularly it relates to a process for the preparation of soluble oligoimide prepolymers which can be used as matrix resins that can be rapidly cured to form stable polyimides with amino end functionalities. The amino functionalized oligoimide telechelics are suitable for conversion into three dimensional polymeric systems through condensation chemistry such as reaction with oligo epoxies (epoxy-imide resins), polyacids (polyamide imides) and polyhalogenated compounds (poly amine - imides) to form crosslinked structures having enhanced thermal stability and mechanical strength. The polymers prepared by the process of this invention can be used as materials in advanced composites having high temperature stability.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">India Patents</style></work-type></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>25</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Dwivedi, Mayank</style></author><author><style face="normal" font="default" size="100%">Rao, Locanindi Hari Sarvothama</style></author><author><style face="normal" font="default" size="100%">Reddy, Krishna Mohan Srinivasulu</style></author><author><style face="normal" font="default" size="100%">Dhanasekharan, Janakiraman</style></author><author><style face="normal" font="default" size="100%">Rao, Bevara Madhusudana</style></author><author><style face="normal" font="default" size="100%">Kumar, Sriperambudur Rajesh</style></author><author><style face="normal" font="default" size="100%">Ponrathnam, Surendra</style></author><author><style face="normal" font="default" size="100%">Chelanattukizhakkemadath, Raman Rajan</style></author><author><style face="normal" font="default" size="100%">Tayal, Rajivkumar</style></author><author><style face="normal" font="default" size="100%">Qureshi, Moham</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Amino-phenol-formaldehyde resins by in-situ generation of catalyst</style></title></titles><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">JAN</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">2536/DEL</style></number><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Thudi, Lahari</style></author><author><style face="normal" font="default" size="100%">Jasti, Lakshmi Swarnalatha</style></author><author><style face="normal" font="default" size="100%">Swarnalatha, Y.</style></author><author><style face="normal" font="default" size="100%">Fadnavis, Nitin W.</style></author><author><style face="normal" font="default" size="100%">Mulani, Khudbudin Baban</style></author><author><style face="normal" font="default" size="100%">Deokar, Sarika Babasaheb</style></author><author><style face="normal" font="default" size="100%">Ponrathnam, Surendra</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Adsorption induced enzyme denaturation: the role of protein surface in adsorption induced protein denaturation on allyl glycidyl ether (AGE)-ethylene glycol dimethacrylate (EGDM) copolymers</style></title><secondary-title><style face="normal" font="default" size="100%">Colloids and Surfaces B-Biointerfaces</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">1-Cyclohexyl-2-pyrrolidinone</style></keyword><keyword><style  face="normal" font="default" size="100%">Adsorption</style></keyword><keyword><style  face="normal" font="default" size="100%">Alcohol dehydrogenase</style></keyword><keyword><style  face="normal" font="default" size="100%">Alkaline phosphatase</style></keyword><keyword><style  face="normal" font="default" size="100%">allyl glycidyl ether</style></keyword><keyword><style  face="normal" font="default" size="100%">Denaturation</style></keyword><keyword><style  face="normal" font="default" size="100%">ethylene glycol dimethacrylate</style></keyword><keyword><style  face="normal" font="default" size="100%">Glucose dehydrogenase</style></keyword><keyword><style  face="normal" font="default" size="100%">Trypsin</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">FEB</style></date></pub-dates></dates><publisher><style face="normal" font="default" size="100%">ELSEVIER SCIENCE BV</style></publisher><pub-location><style face="normal" font="default" size="100%">PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS</style></pub-location><volume><style face="normal" font="default" size="100%">90</style></volume><pages><style face="normal" font="default" size="100%">184-190</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;The effects of protein size on adsorption and adsorption-induced denaturation of proteins on copolymers of allyl glycidyl ether (AGE)-ethylene glycol dimethacrylate (EGDM) have been studied. Different responses were observed for the amount of protein adsorbed and denatured on the polymer surface for different proteins (trypsin, alchol dehydrogenase from baker's yeast (YADH), glucose dehydrogenase (GDH) from Gluconobacter cerinus, and alkaline phosphates from calf intestinal mucosa (CIAP). Protein adsorption on the copolymer with 25% crosslink density (AGE-25) was dependent not only on the size of the protein but also on the presence of glycoside residues on the protein surface. Adsorption and denaturation of proteins follows the order YADH &amp;gt; trypsin &amp;gt; GDH &amp;gt;&amp;gt; CIAP although the molecular weights of the proteins follow the order YADH &amp;gt; CIAP &amp;gt; GDH &amp;gt; trypsin. The lack of correlation between amount of adsorbed protein and its molecular weight was due to the presence of glycoside residues on CIAP and GDH which protect the enzyme surface from denaturation. Enzyme stabilities in aqueous solutions of 1-cyclohexyl-2-pyrrolidinone (CHP) correlate well with the trend in denaturation by the copolymer, strongly suggesting that hydrophobic interactions play a major role in protein binding and the mechanism of protein denaturation is similar to that for water-miscible organic solvents.
