Understanding protein structural excursions using residue networks and implications on biological function
The information required for a protein structure to fold into the native conformation is encoded in its sequence. Studying protein structures help to understand their biological function. Molecular interactions between ...
Deep mutational scanning to enhance immunogenicity and map antibody responses to HIV-1
Vaccines have proven effective against numerous viral diseases, yet the development of a
successful vaccine for Human Immunodeficiency Virus (HIV-1) remains elusive. A key
immunogen for vaccine design is the surface ...
Role of the unstructured N-terminal region and interacting proteins on the function of Mycobacterium tuberculosis σA
A distinctive feature of the bacterial RNA polymerase is the modular organization. The core of this enzyme, comprised of a dimer of the α subunit assembles with the β, β', and ω subunit. The core RNA polymerase enzyme ...
Understanding structure, function, and dynamics in macromolecular complexes
In the scope of my thesis work, a concerted effort was undertaken to elucidate bi-
ological functions through the lens of structural analysis, employing protein dy-
namics. The role of protein dynamics in shaping and ...
Solution NMR studies of a potent subtilisin inhibitor from Budgett’s frog and the catalytic subunit of AHAS
This thesis involves a detailed structural study of two molecular systems, a small disulfide-rich peptide LL-TIL and a large catalytic subunit of AHAS.
Subtilisin inhibitors play an important role in fighting against ...
Understanding the interaction mechanism of bacterial virulence factors and effector proteins with host lipid membrane using single particle cryo-electron microscopy
Pathogenic bacteria employ an array of biological macromolecules and cellular
structures that help in the initiation and progression of disease in host organism.
These ‘virulence factors’ can either be secreted by the ...
Role of HCN Currents (Ih) in Epileptiform Activity in Subicular Neurons
Subicular burst firing neurons are established as primary instigators of seizure onset and propagation in Temporal Lobe Epilepsy (TLE), a form of focal epilepsy that accounts for approximately 60% of all epilepsy cases in ...
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 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), ...
