Three-dimensional structures of proteins provide insights into the mechanisms of macromolecular assembly, enzyme catalysis and mode of activation, substrate-specificity, ligand-binding properties, stability and dynamical ...

The emergence of drug resistant strains of Plasmodium has given a new face to the old disease, malaria. One of the approaches is to block metabolic pathways of the pathogen. The current thesis describes the X-ray ...

Lectins, multivalent carbohydrate-binding proteins of non-immune origin, have the unique ability to decode the information contained in complex carbohydrate structures of glycoproteins and glycolipids by stereo-specifically ...

Influenza is an important respiratory pathogen that infects several million people each year. Currently available flu vaccines have to be updated regularly in order to be effective as the virus changes its composition by ...

Disulfides are the primary covalent interactions within a protein molecule that connect residues which are sequentially distant. Naturally occurring disulfides enhance the stability of the protein by destabilization of ...

Protein Tyrosine Phosphatases (PTPs) initiate, modulate and terminate key cellular processes by dephosphorylating phosphotyrosine (pY) residues on signaling proteins. The coordinated action of PTPs with their cognate ...

X-ray crystallography is one of the most powerful tools for the elucidation of the structure of biological macromolecules such as proteins and viruses. Crystallographic techniques are extensively used for investigations ...
