- Summer Research: Production and purification of protein for structure determination using X-ray Crystallography [ Dr. Marie Fraser ,; May 2014 - Aug 2014]
Abstract: ATP-citrate lyase (ACLY) is the enzyme that 1) links energy metabolism from carbohydrates to the production of acetyl-CoA in the cytoplasm of animals and 2) closes the reductive citric acid cycle in bacteria that use this cycle to fix carbon dioxide. To date, we have determined the crystal structure of two-thirds of ACLY in complex with the substrate citrate, the inhibitor tartrate and the product ADP-Mg2+. These structures answered the question of where the organic acid bound to this member of the family of succinyl-CoA synthetase-related enzymes; but the truncated protein did not bind CoA. Our goal is to determine the structure of a longer form of ACLY, which will also show the binding sites of CoA and acetyl-CoA.
- International Genetically Engineered Machine (iGEM) Progect 2013: Combating Shiga-toxin: A synthetic biology approach [ Dr. Nitish Mahapatra , Dr. Karthik Raman ,; Mar 2013 - Sept 2013]
Abstract: Shiga toxin, a worldwide menace, has killed over 1 million people to date and continues to afflict almost 150 million people each year. Currently, there is no treatment for Shiga toxicosis and it leads to complications in the human system like hemolytic uremic syndrome (HUS) and renal failure. Here, we propose a two-fold, novel synthetic biology approach to combat the lethal effect of the toxin. We aim to neutralize the already produced toxin through a nine amino acid Gb3 mimic peptide. We have engineered the Gb3 mimic along with a cellular export signal (ompF) downstream of AHL(quorum sensing molecule) inducible promoter (pLuxR). We also plan to prevent further toxin production by inhibiting the biofilm formation of shigatoxigenic E.coli using indole-3-acetaldehyde (I3A). We expect to validate our approach through functional assays and in silico modelling. Our findings can potentially initiate a new perspective of tackling Shiga toxicosis using synthetic biology tools.

- Characterization of Chromogranin A protein and studying its interaction with Hsp. [ Dr. Nitish Mahapatra ,; Dec 2012 - Till Date]
Abstract: Cardiovascular diseases (coronary heart disease, heart failure, stroke etc.) affect a large section of the adult population and are the leading causes of morbidity and mortality in many countries including India. Chromogranin A (CHGA) is ubiquitously expressed in secretory cells of the endocrine, neuroendocrine, and neuronal tissues. Although this protein has long been known as a marker for neuroendocrine tumors, its role in cardiovascular disease states including essential hypertension (EH) has only recently been recognized. Our plan focuses on purifying and investigating the functional behaviour of the protein and study its interactions with heat shock proteins (Hsp 70).
- Summer Internship: Investigating the function of Mom protein using site-directed mutagenesis. [ Prof. V Nagaraja,; May'12 - Jun'12]
Abstract: Bacteriophage Mu or phage Mu is a temperate bacteriophage that infects Escherichia coli and a wide range of other gram-negative enteric bacteria. Mu is a phage that replicates by transposition, which happens on induction of the quiescent phage or during lytic infection. Thus, replication of Mu phage occurs through a series of replicative transposition events. There is one novel feature of Mu that expands its host range which happens through unusual host-range expansion mechanism because of the gene of our interest, the mom gene. The gene mom stands for modification of mutator. This gene helps in modifying the DNA of the phage and acts as a saviour to the phage. The mechanism of modification is a post-replicative DNA modification. This function helps the viral genome resistant to cleavage by a wide variety of restriction endonucleases. Thus, mom gene acts as a protective sheath against nucleolytic attack when the Mu genome infects a bacterial cell possessing host specificity or RM (restriction modification) system different from the one in which the phage had been last grown. Our objective is to purify the Mom protein and investigate its function using site-directed mutagenesis with wild-type as the control.
