Structure analysis of lectin and lectin-like domains from Entamoeba histolytica
Lectins are a diverse group of proteins which can recognize different types of carbohydrates specifically and reversibly. Though first characterized in plants, lectins have now been identified in all other forms of life. ...
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 ...
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 ...
Small Heat Shock Proteins from Bacteria and a Bacteriophage
Proteins can unfold during heat and other types of stress and tend to aggregate with subsequent loss of function. This event is prevented by small Heat Shock Proteins (sHSPs) acting as molecular chaperones. sHSPs do not ...
Crystallographic and analytical ultracentrifugation studies of the E. coli acetohydroxy acid synthase I enzyme
This thesis ellucidates the mechanism of activation and regulation of AHAS I
enzyme from Escherichia coli that was characterised using crystallographic and
sedimentation velocity analytical ultracentrifugation studies.
AHAS ...
Understanding intramolecular signal transduction in regulated proteases of the High Temperature Requirement A family
Protein homeostasis in all organisms is a complex process involving regulatory mechanisms that govern protein synthesis, post-translational events and degradation. The protein degradation mechanism serves multiple functions ...
Resource allocation during Flavivirus lifecycle
Single-stranded RNA virus infection cycle progresses by resource (viral RNA) allocation to segregated macromolecular complexes: host ribosomes (translation), viral RNA polymerase (replication) and viral structural proteins ...
Development and application of sequence-based approaches for recognition and functional characterization of protein kinases
Protein kinases, the third most populous protein family, are a major class of enzymes that regulate a wide range of cellular processes by phosphorylating multiple cellular proteins. There are many conserved sequence motifs ...
Structural and functional studies on DNA damage inducible protein 1 (Ddi1) from protozoa
Structural and functional investigations on DNA-damage inducible protein1 (Ddi1) from Entamoeba histolytica, Trypanosoma cruzi and Toxoplasma gondii have been carried out. Ddi1 belongs to the ubiquitin receptor family of ...
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 ...
