Computational Investigation of Heterogeneous Lateral Organisation in Biological Membrane
The study of lateral heterogeneity on membrane surface has come a long way from the fluid mosaic model. Simulations and experimental studies have observed non-random mixing of lipids and proteins in the membrane. In this ... -
Design, Synthesis, and Bioactivity of Thioamidated Macrocyclic Peptides
The work presented in this thesis describes the comprehensive study related to thioamidated macrocyclic peptides. We study the underexplored class of peptide bond isostere; thioamides in the context of small macrocyclic ... -
Insights into the conformational stability & pharmacology of peptides through side chain and backbone modification
The first part of the work presented in the thesis deals with CH-pi interaction, which is a lesser-known non-covalent interaction in proteins. We identified several CH-pi donor-acceptor pairs involving amino acids side ... -
Network Heterogeneities, Intrinsic Plasticity and Decorrelation in the Dentate Gyrus
A central premise for research in neuroscience is to mechanistically decipher the physiological roles of the brain in effectuating learning and memory. The tripartite framework that is at the core of learning and memory ... -
Protein-small molecule interactions: Structural insights and applications in computational drug discovery
Deviation from normal healthy conditions, termed as disease, can often be triggered due to the malfunctioning of proteins. Modulating the functions of proteins by administering therapeutic agents (drugs) may alleviate the ... -
Scanning mutagenesis studies of HIV-1 Env immunogenicity and structure
Human Immunodeficiency Virus type 1 (HIV-1) is the etiological agent of Acquired Immunodeficiency Syndrome (AIDS). AIDS is a global pandemic with 36.7 million people living with HIV-1 all over the world and approximately ... -
Solution structures and interaction studies of mycobacterial MazEF6 toxin-antitoxin system
Toxin-Antitoxin (TA) systems are stress response systems found on plasmids and chromosomes of bacteria and archaea. They are involved in important functions such as plasmid maintenance, programmed cell death, persister ... -
Stimulus statistics and HCN current mediated resonance sets the scale of input-output mapping in Stellate cells of the Medial Entorhinal Cortex
The functional significance of the computations performed by Stellate cells of the Medial Entorhinal Cortex, proven time and again, makes them insightful, yet intriguing. The gradients of the intrinsic properties of these ... -
Structural and biochemical studies on mycobacterial Uracil-DNA glycosylase (Ung) and MutT1, key proteins involved in maintaining the genomic integrity in Mycobacteria
Maintaining genomic integrity is indispensable for the survival and propagation of an organism. Failure to do so can cause mutations involving structural and functional aberrations, leading to severe diseases. The causative ... -
Structural and Biophysical studies to evaluate the influence of oligomerization on biomolecular function
Oligomeric proteins are more common than monomers. This aspect of molecular evolution substantially contributes to functional diversity and the acquisition of features such as cooperativity and regulatory mechanisms. Not ... -
Structural and functional insights into hybrid AT-less megaenzyme synthase (NRPS) and DNA-MsDps2 complexes using single particle cryo-EM
Microorganisms, mainly bacteria and fungi, are the producers of structurally diverse, complex organic compounds called as secondary metabolites. These metabolites include polyketides (PKs), non-ribosomal peptides (NRPs), ... -
Structural and functional insights of biological macromolecules associated with infectious diseases – single particle cryo-electron microscopy based studies
In the global context, particularly in India, the two most important infectious diseases among many others are Tuberculosis (TB), an age-old disease and COVID-19, a new-age disease. This thesis focuses on some of the key ... -
Structural and mechanistic studies on Staphylococcal RNA degrading enzymes and multienzyme complexes
RNA degrading enzymes and multi-enzyme complexes govern a variety of cellular processes. The role of these enzymes and multi-enzyme assemblies has been suggested to govern gene expression levels in bacteria with modulations ... -
Structural insights into assembly and regulation of HigBA toxin-antitoxin system from Escherichia coli
In the last few decades, bacterial Toxin-antitoxin (TA) systems have been identified to play crucial roles in bacterial survival under stressful conditions and virulence. TA systems are pair of genetic elements where one ... -
Use of strategically designed protein-like sequences in structure and function recognition
The advent of high fidelity protein sequencing techniques has led to a considerable wealth of sequence data. However, the number of proteins with information on 3-D structure and functional features available is considerably ...
