Cross polarisation dynamics in solid state nuclear magnetic resonance
In this chapter, Floquet theory was employed to describe the SAP (Selective Averaging Pulse) experiment. Restriction of the CP (Cross Polarization) contact time to part of the rotor period and the application of additional ... -
Crystal Structure Analysis of a (B/a)8-TIM Barrel Enzyme and Its Mutants : Insights into the Role of Interactions Between Termini in Influencing Protein Stability. Experimental and Computational Study of Protein-Surface-Pockets Occluded by Tryptophan Side-Chains
Xylanases (EC 3.2.1.8) are glycosyl hydrolases that catalyze the hydrolysis of internal β-1,4 glycosidic bonds of xylan backbones, and have potential economical and environment friendly applications in the paper pulp, food, ... -
Crystal structure of a light-harvesting protein C-phycocyanin from spirulina platensis and bioinformatics analysis of beta-bulge turns in proteins
The conclusions for the crystal structure of light-harvesting phycobiliprotein, C-phycocyanin from an important cyanobacterium, Spirulina platensis, are summarized as follows: We have solved the three-dimensional structure ... -
Crystal Structure Of Abrus Precatorius Agglutinin-I (APA-I) : Insights Into The Reduced Toxicity Of APA-I In Relation To Abrin. Formation Of Ordered Nanotubes Through Self Assembly In The Crystal Structures Of Dipeptides Containing α. β-dehydrophenylalanine
(2009-07-22)Ribosome Inactivating Proteins (RIPs) are protein or glycoprotein toxins that bring about the arrest of protein synthesis by directly interacting with and inactivating the ribosomes. Such toxins are in general, of plant ... -
Crystal Structure of an Effector Histone Methyltransferase Rv2067c from Mycobacterium tuberculosis H37Rv: Structural Insights into Context-Dependent Substrate Recognition Structure and Dynamics of a GNAT Family Protein Acetyltransferase HP0935 from a Gastric Pathogen Helicobacter pylori 26695
Methylation of histones is one of the important gene regulation mechanisms in eukaryotes. Histone methylation has a role in immune response to the invading pathogens. Pathogens implement effector proteins that evade host ... -
Crystal Structure Of Mycobacterium Tuberculosis Histone Like Protein HU And Structure Based Design Of Molecules To Inhibit MtbHU-DNA Interaction : Leads For A New Target. Structure Aided Computational Analysis Of Metal Coordinated Complexes Containing Amino Acids And Organic Moieties Designed For Photo Induced DNA Cleavage
(2015-08-17)In bacteria, nucleoid associated proteins (NAPs) represent a prominent group of global regulators that perform the tasks of genome compaction, establishing chromosomal architecture and regulation of various DNA transactions ... -
Crystal Structures of Native and AdoMet Bound rRNA Methyltransferase from Sinorhizobium meliloti : Structural Insights into rRNA Recognition. Evolutionary, Structural and Functional Studies on Nucleoid-Associated Proteins HU and IHF
DNA- and RNA-binding proteins play a central role in gene regulation, which includes transcriptional control, alternative splicing, post-translational and transcriptional modifications like methylation and acetylation among ... -
Crystal Structures Of Native And Xylosaccharides-Bound Alkali Thermostable Xylanase From An Alkalophilic Bacillus SP. NG-27: Structural Insights Into Alkalophilicity. Analysis Of C-H...O Hydrogen Bonds In Helices Of Globular Proteins
(2007-11-21)Xylanases are xylan-degrading enzymes, belong to glycosyl hydrolases (GH). Xylanases from the two major families 10 (GH10) and 11 (GH11) catalyze the hydrolysis of internal β-, bonds of xylan backbone. Xylan is the second ... -

De Novo design of protein secondary and super-secondary structural elements : Insights from the crystal structures of a,B-dehydrophenylalanine containing oligopeptides- a novel weak-interaction based design strategy
The surface complementarity (charge, structural, etc.) plays a vital role in molecular recognition and association. It appears that the modes of interaction between aliphatic–aliphatic, aliphatic–aromatic, and aromatic–aromatic ... -
Dendrimer Interactions with Cell Membrane and Pore Forming Toxins
Dendrimers are hyper-branched polymeric nanoparticles with a central core molecule connected by successive dendritic branching layers. The structure controlled parameters of den-drimers such as size, shape, surface chemistry, ... -
Density functional and computer simulation studies of colloidal suspensions
Colloidal suspensions of polyballs (polystyrene spheres) are good model systems for the study of both structural and dynamical properties of solids and liquids because the pair-wise interaction between the colloidal particles ... -
