Area of Research:
Molecular Biology, Protein Engineering, Structural and Functional Proteomics of Carbohydrate active enzymes and other industrially important microbial enzymes.
I) Ongoing Research:
A. Microbial Diversity for industrially useful microorganisms from North-East India.
B. Molecular, structural, functional and biochemical analysis of Carbohydrate Active Enzymes.
C. Microbial conversion of cellulosic agrowaste to bioethnol using microbial cultures, natural and recombinant cellulases and hemicellulases for bioethanol production.
II) At Faculty of Veterinary Medicine, Lisbon, Portugal I was involved in various projects:
III) At BISR, Jaipur, I worked on a project on Microbial Biodiversity of saline lakes and desert regions of Rajasthan, India. The aim was to selectively screen the enzymes of bioprocess importance such as hydrolases (lipase, protease, xylanases and cyclodextrin glycosyltransferase) from the isolates. We isolated few strains from soil samples of Asia's largest salt lake (Sambhar Lake), capable of growing at high pH and at saturating concentrations of salt.
IV) I worked on Molecular Genetics of RNA at WSU, Detroit. I was involved in determination of structural and functional relationship of the 790 loop and 1400-1500 regions of 16S ribosomal RNA of E. coli. The 790 loop is a conserved hairpin located between positions 786 and 796 of 16S rRNA and is required for ribosomal function. With the development of a method for `instant evolution' in which random mutagenesis and in vitro selections were used to identify both structural and functional features of 790 loop and 1400-1500 bp regions. I performed the random mutations at 1401, 1404, 1497 and 1500 positions of 16S rRNA in pWK1 plasmid separately and then random mutations at all four positions together in pRNA123 plasmid. I accomplished the transfer of nine single 790-loop mutants of 16S rRNA from plasmid pRNA122 to pRNA123, to study the functional aspects of ribosome.
V) At OSU, Columbus, I worked on purification of a newly identified methyl branched chain fatty acid synthesising enzyme from Mycobacterium tuberculosis H37Rv. Mycobacterial cell wall contains a variety of lipids with many types of multiple methyl-branched fatty acids. The aim was to elucidate the mechanisms involved in the biosynthesis of these lipids and to test their possible functions in the host-pathogen interaction. I was involved in the purification of a mycocerosic acid synthase, identification of products generated, seeking the identity of the gene that encodes the synthase in the genomic data bank using the protein sequence and in determining the biochemical and functional consequences of knocking out of this gene. The results would help identify the cell wall lipids critical for pathogenesis that might be suitable targets for new antimicrobial drugs.
VI) At UCD, Dublin, I investigated co-operative behaviour of hybrid hexamers of different mutant forms of glutamate dehydrogenase (GDH) from Clostridium symbiosum. Hybrid hexamers were constructed by in vitro subunit hybridisation. Clostridial GDH is an allosteric enzyme and is hexameric and has only one type of subunits. This implies that allosteric effects are mediated by interactions among six identical subunits. To study this defined inter-subunit hybrids were constructed in which some of the subunits were functionally disabled with respect to substrate binding or catalysis. The results demonstrated that it is possible to dissect the basis of allosteric interaction in GDH by constructing hybrid hexamer approach.
VII) In doctoral research at IIT Kanpur, I worked on dextransucrase from Leuconostoc mesenteroides NRRL B-512F. I discovered a new medium for the maintenance of culture and a new medium for higher production of enzyme. I developed a simple and effective method for purification by fractionation using polyethylene glycol 400. The total amino acid composition of dextransucrase was determined. I established for the first time by chemical modification studies using pyridoxal 5'-phosphate, o-phthalaldehyde and 2,4,6-trinitrobenzenesulphonic acid that a lysine residue present at the active site is essential for enzyme activity.
VIII) In M.Tech. project at IIT Delhi, I worked on isolation and purification of coenzymes NADH and ATP from Saccharomyces cerevisiae. I developed a method to isolate and purify these adenine coenzymes. The cells were permeabilised by ether for the recovery of coenzymes. The purification was carried out by affinity-ultrafiltration technique using alcohol dehydrogenase and hexokinase for NADH and ATP respectively, as affinity molecules.
