I am working on Mycobacterium tuberculosis system. My work is focused towards the structural characterization of Mycolic acid methyl transferases A1 (MmaA1) Protein in M. tuberculosis. Tuberculosis is one of the most threatening disease worldwide. MmaA1 protein is involved in pathway of mycolic acid biosynthesis acid which resides inside the cell wall of M. tuberculosis. Mycolic acid provides drug resistance to a wide range of antibiotics, help in survival through physiological stress conditions such as dehydration. MmaA1 is involved in the conversion of a cis-olefin into trans-olefin with concomitant introduction to any allylic methyl branch at the proximal position to both methoxy and keto-mycolic acids. This will involve structural study of MmaA1 protein using X- ray crystallography along with in-silico identification of potential MmaA1 inhibitor molecules.
I am working on Helicobacter pylori system. It is a common bacterium that affect more than 50% of the world’s population. H. pylori infection is found to be a major risk factor for gastritis, peptic ulcer and gastric cancer. In H. pylori, I am dealing with a protein HppA, a sole bacterial 5’ nucleotidase that has a narrow spectrum of phospho-monoesterase activity. HppA catalyses the conversion of FldA, an internal electron acceptor for pyruvate: oxido-reductase(POR) complex, from holo to apo form. Hence, it plays a major role in transfer of electron from acetyl CoA to electron transport chain and therefore, found to be essential for bacterial survival. Structural characterisation of HppA using x ray crystallography would help in understanding the catalytic mechanism of enzyme. Identification and in-silico designing of small inhibitor molecules will foster towards the development of long range inhibitors. This study will pave the way to an in-depth perspective on H. pylori striving mechanism in the host cells and developing drug resistance in the bacterium.

Dr. Udit Soni (Ph.D., IIT- Delhi)
Assistant Professor (Department of Biotechnology, TERI SAS)
Dr. Udit’s research focuses on the synthesis of nanocrystals for the study of fundamental science and economic applications. He is actively involved in research and development of new materials exhibiting bright luminescence and light harvestation; the ultimate aim being applications in photocatalysis, LEDs, photovoltaics, biological labeling and sensor technology applications. Dr. Udit is also working on developing non-toxic materials as an alternative to cadmium chalcogenides.
Dr. Vemulapati Bhadra Murthy (Ph.D., Mangalore University)
Assistant Professor, Department of Biotechnology, Koneru Lakshmaiah Education Foundation (K L University), Greenfields, Vaddeswaram – 522502, Guntur, A.P., India.
Dr. Murthy is a molecular virologist with ten years of research experience in plant and animal virology. He is actively involved in teaching and research in topics related to biotechnology and biochemistry. Dr. Murthy was a Post-Doctoral Associate in USDA-NIFA funded project in Dr. Hanu Pappu’s Lab in Department of Plant Pathology, Washington State University, Pullman, U.S.A from 2009-2011. Later he joined as a Staff Scientist (Doctoral Level) in a NIH funded research project in Dr. Hector Aguilar-Carreno’s Lab at Paul G. Allen School for Global Animal Health, Washington State University, Pullman, U.S.A. from 2009-13. Currently, Dr. Murthy is working at KL Education Foundation as an Assistant Professor and his areas of research are development of antiviral therapeutics, molecular and immunological diagnostic platforms. Dr. Murthy is collaborating with SMBL group on structural, biophysical and in-silico characterization studies of viral proteins.
I am a doctoral student at Deakin University, Australia (in collaboration with TERI School of Advanced Studies). My Ph.D. research work with Dr. Udit Soni and Prof. David Cahil is focused on the synthesis and modification of the various nanomaterials for the delivery of the biomolecules/chemicals to the plant system for the development of the desired improvements (e.g. genetic modification, boosting growth and yield, disease resistance). We are fabricating nanomaterials for the delivery of fertilizers, hormones, and biomolecules such as DNA, RNA, and protein. I am also involved in deciphering the molecular architecture of macromolecules which contribute in pathogenesis and immunity through X-ray crystallography, gene and protein engineering, biochemistry, and nanotechnology (e.g. tuberculosis and dengue disease) with Dr. Madhurantakam at SMBL, TERI SAS.
