Accessibility of the various regions of β-lactoglobulin during thermal unfolding and refolding
(Indian Society for Surface Science and Technology, 2004)Structure of the refolded β-lactoglobulin has been compared with that of native β-lactoglobulin by measuring the accessibility of the various regions of the protein molecule. Site selective fluorescence labelling was ... -
Application of sulfamic acid as an eco-friendly catalyst in an expedient synthesis of benzimidazoles
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-05-01)Sulfamic acid, an eco-friendly and zwitterionic solid, proved to be a very efficient catalyst for the reaction of ortho-phenylenediamine with aryl aldehydes in ethanol at room temperature to furnish both 1-arylmethyl-2-aryl- ... -
AtPoiA, a homogue of mammalian DNA polymerase in Arabidopsis thaliana, is involved in the repair of UV-B induced DNA damage through the dark repair pathway
(OXFORD UNIV PRESS, 2011-02)Plants are constantly exposed to a wide range of environmental genotoxic stress factors including obligatory exposure to UV radiation in sunlight. Here, we report the functional characterization of a DNA repair protein, ... -

Chaperone-mediated inhibition of tubulin self-assembly
(Elsevier B.V., 2007-04-01)Molecular chaperones are known to play an important role in facilitating the proper folding of many newly synthesized proteins. Here, we have shown that chaperone proteins exhibit another unique property to inhibit tubulin ... -
Combating shigellosis through an understanding of the role of some membrane proteins in drug resistance in Shigella.

Computational modeling of differences in the quorum sensing induced luminescence phenotypes of Vibrio harveyi and Vibrio cholerae
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011-04-07)Vibrio harveyi and Vibrio cholerae have quorum sensing pathways with similar design and highly homologous components including multiple small RNAs (sRNAs). However, the associated luminescence phenotypes of strains with ... -
Crystal structure and microstructure of cholesteryl oleyl carbonate
(ELSEVIER IRELAND, 2011-01)The crystal structure as well as the microstructure, i.e., size and strain, of crystallites of cholesteryl oleyl carbonate was determined from X-ray powder diffraction data. The X-ray line broadening was analyzed through ... -
Differential recognition of natural and nonnatural substrate by molecular chaperone α-crystallin - A subunit exchange study
(JOHN WILEY & SONS INC, 2007-02-05)alpha-Crystallin is a molecular chaperone that recognizes proteins substrates in stress. It binds to the unstable conformer of a large variety of related or unrelated substrates and thus prevents them aggregating and holds ... -
Dipole-induced chiral smectic-C phase in a eutectic mixture of cholesterol esters
(ELSEVIER SCIENCE BV, 2005-07-20)Both cholesteryl oleate (CO) and cholesteryl oleyl carbonate (COC) are thermotropic mesogens with a general cooling phase sequence: isotropic cholesteric -> smectic crystal. They are almost identical with respect to molecular ... -
Direct extracellular interaction between the early secreted antigen ESAT-6 of Mycobacterium tuberculosis and TLR2 inhibits TLR signaling in macrophages
(NATURE PUBLISHING GROUP, 2007-06-02)Expression of early secreted antigenic target protein 6 (ESAT-6) by Mycobacterium tuberculosis is associated with lower innate immune responses to infection. Here we show that ESAT-6 inhibited activation of transcription ... -
Effect of fatty acid supplementation on some biochemical properties of Saccharomyces cerevisiae
(Bose Institute, Kolkata, 1985) -
Effect of fish oil on induced atherosclerosis with particular reference to platelet aggregation and lipoprotein function.
(Bose Institute, Kolkata, 1990) -
Effect of Methylglyoxal Modification of Human alpha-Crystallin on the Structure, Stability and Chaperone Function
(SPRINGER, 2010-11)alpha-Crystallin functions as a molecular chaperone and maintains transparency of eye lens by protecting other lens-proteins. Non-enzymatic glycation of alpha-crystallin by methylglyoxal, plays a crucial role on its chaperone ... -
Efficient scheduling using complex networks
(arXiv.org, 2012-06-03)We consider the problem of efficiently scheduling the production of goods for a model steel man- ufacturing company. We propose a new approach for solving this classic problem, using techniques from the statistical physics ...
