Research:

The work encompasses structural biology, proteomics and bioinformatics. Both experimental and theoretical techniques are used for getting insight into aspects of protein structure, function and regulation.

1) Nobel Laureate Linus Pauling had proposed important protein secondary structures, a-helix and b-sheet. From an exhaustive analysis of protein structures we have discovered a new secondary structure, which because of its shape is termed topi (hat in many Indian languages). Thus we have introduced an Indian term in scientific lexicon (Dhar J, Kishore R and Chakrabarti P. Scientific Reports, 6:31483 (2016).

2) Following the tradition of GN Ramachandran we have done extensive work on protein structure, conformation and weak interactions that stabilize the native fold. A review article with authors from three other countries on C-H···p  interactions (Nishio M, Umezawa Y, Fantini J, Weiss MS and Chakrabarti P. Phys. Chem. Chem. Phys. 16, 12648 (2014)) has been highly acclaimed.

3) We have been involved in understanding the process of molecular recognition by analyzing the physicochemical and evolutionary properties of interfaces formed in protein-protein/DNA complexes. Our dissection of the interface into core and rim (Chakrabarti P and Janin J. Proteins, 47, 334 (2002)) is now referred to as CJ model (Levy E. J Mol Biol 403, 660 (2010)). This is one of the most highly cited papers from the institute (~600 citations). The residues in the core are more conserved than those in rim, which has led to the development of an algorithm of for predicting the hotspot residues in interfaces (Guharoy M and Chakrabarti P. Proc. Natl. Acad. Sci. USA, 102, 15447 (2005)).

4) Many of the webservers (on protein-protein interaction) developed in the lab (http://www.boseinst.ernet.in/resources/bioinfo/stag.html) are being widely used (Saha RP, Bahadur R, Pal A, Mandal S and Chakrabarti P. BMC Struct. Biol. 6, 11 (2006)).

5) We are involved in crystallographic analysis of a number of interesting proteins, such as CII from bacteriophage lambda, which is the deciding factor in which of the two alternative modes (lysis or lysogeny) bacteriophage lambda develops. The structure explains why this transcription activator binds a direct repeat DNA sequence (Datta AB, Panjikar S, Weiss MS, Chakrabarti P and Parrack P. Proc. Natl. Acad. Sci. USA, 102, 11242 (2005)).

6) Another topic of interest is the structural proteomics of Vibrio chholerae. Structures have been elucidated for HlyU (transcriptional activator of the hemolysin gene hlyA) (Mukherjee D, Datta AB and Chakrabarti P. Biochim. Biophys. Acta 1844, 2346-2354 (2014)) and PIMT (a repair enzyme) (Chatterjee T et al. Arch. Biochem. Biophys. 583, 140 (2015)). EMSA has been used to delineate the DNA binding sequence (173 bp upstream of hlyA promoter), and mutational studies carried out to identify the residues in the recognition helix and the wing region of HlyU involved in the interaction (Mukherjee D, Pal A, Chakravarty D and Chakrabarti P. Nucleic Acids Res. 43, 1407-1417 (2015)). The effect of virstatin on the DNA binding property of ToxR, a transcriptional activator of two major virulence factors for cholera pathogenesis, cholera toxin (CT) and toxin coregulated pilus (TCP), has been elucidated.

7) Our work involving the antimicrobial and anti-tumor activity of ZnO nanoparticles and their surface-coated derivatives is likely to find niche applications in pharmaceutical industry (Sarwar S, Chakraborti S, Bera S, Sheikh IA, Hoque KM and Chakrabarti P. Nanomedicine, 12, 1499-1509 (2016)). The effect of morphology and size of gold nanoparticles on the growth of V. cholerae biotypes and accessory cholera enterotoxin (Ace) have been studied using biophysical methods and animal studies (Chatterjee T, Chatterjee B, Saha T, Hoque KM and Chakrabarti P. Biochem Biophys Acta, 1861, 977 (2017)). The bacterial growth kinetics has been modeled to incorporate the antibacterial effect of silver nanoparticles (Chatterjee T, Chatterjee BK, Majumdar D and Chakrabarti P. Biochim. Biophys. Acta, 1850, 299 (2015)).

8) Biophysical techniques and MD simulations have been used to understand the binding of small molecules to proteins and the dynamics of binding (Chakraborti S, Dhar G, Dwivedi V, Das A, Poddar A, Chakraborti G, Basu G, Chakrabarti P, Surolia A and Bhattacharyya B. Biochemistry 52, 7449 (2013)). In silico mutations and molecular dynamics have been used to understand the importance of flexibility in the N-terminal actin-binding domain (Chakravarty D, Chakraborti S and Chakrabarti P. Proteins, 83, 696 (2015)).
