Chemistry
The major contribution to research in protein chemistry has been in the areas of protein ligand binding, protein isolation and characterization and protein structure analyses at IIT Kharagpur. Over the years this laboratory has become as an active center of research with generous support from funding agencies. Many research projects including many collaborative projects have been undertaken in interdisciplinary areas. Till date 17 Ph.D. students have been guided. The unique feature of the work is the blend of experimental protein chemistry with in-depth structural analysis.
The major areas are:
Protein aggregation studies: Aggregation studies currently underway are involving human serum albumin, lysozyme and ribonuclease A. We have established that Cu(II) plays a vital role in the fibrillation process of human serum albumin and lysozyme. Effects of a static electric field on the disruption of fibrils have been reported recently.
Isolation and characterization of modified γ-crystallin (HGCc): Modified γ-crystallin (HGCc) has been isolated from the discarded cataractous emulsion of patients. Briefly, pooled lens emulsions were centrifuged followed by lyophilization of the supernatant and subsequent dialysis. The dialyzed emulsion was purified by gel filtration and characterized for further study.
Protein ligand binding: Novel studies with angiogenin indicated that the process of angiogenesis, the capacity to form blood vessels, was inhibited by polyphenols present in green tea. The polyphenols behave as noncompetitive inhibitors of Ribonuclease A. It was found that the copper complexes formed with the two gallate containing polyphenols were better inhibitors of the ribonucleolytic activity than the polyphenols.
