Glycan-binding proteins, glycosyltransferases and glycoconjugates.


The broad research interests of our group are in the interface of glycobiology and molecular biology with specific emphasis on elucidating molecular details involving glycoconjugate-lectin interactions in various biological phenomena. Past and ongoing research projects include understanding the ligand binding specificity of intelectins, understanding the glycan-binding specificity and targeting functions of microbial F-type lectin domains, exploring the taxonomic diversity and carbohydrate-active proteins of the human gut microbiome in Indian individuals from different geographic regions and dietary habits, biochemical studies on microbial flagellin O-glycosyltransferases and alginate lyases, and, expression and characterization of sialyltransferases for synthesis of medically relevant oligosaccharides.
