Genome stability, DNA replication and stress response in Bacteria

Research Description:
Our research focuses on how living organisms accurately duplicate and process their genetic information by regulating central dogma processes- replication, transcription and translation. These processes lie at the heart of all cellular activities and are crucial for survival and genome stability. We study these processes in the Gram-positive bacterium Bacillus subtilis and the Gram-negative bacterium Escherichia coli. They have simpler modes of replication and transcription than eukaryotes and are highly amenable to genetic manipulation. We take a global approach, combining genetic, genomic, biochemical, and computational methods to uncover essential, previously unknown aspects of central dogma regulation: identifying a molecular interface between the DNA replication machinery and its cellular milieu; understanding the conflicts between replication and transcription; and discovering how evolutionarily divergent bacteria utilize a ubiquitous molecule for stress-resistance. Because the fundamentals of information-processing mechanisms are conserved across all domains of life, our work in bacteria is broadly applicable to other less-tractable systems.
