Research in our laboratory is focused towards understanding how bacteria elongate, divide, and split their cell walls during cell cycle to successfully generate two equal daughter cells. We take a multi-disciplinary approach including genetics, biochemistry, cell biology, and genomics to address these questions. We use a well-known Gram-negative rod-shaped bacterium Escherichia coli as our primary model system. Our most significant contribution in this field was identification of a rate-limiting cleavage step in the growth and synthesis of peptidoglycan, a unique constituent of bacterial cell wall. We expect that our work facilitates better understanding of fundamental aspects of bacterial physiology thereby providing novel strategies for development of alternate antimicrobial therapeutics.
