Ph.D. project Thesis Title: - “Molecular mechanism(s) underlying multipartite genome maintenance in radiation resistant bacterium Deinococcus radiodurans R1” I pursued my Ph.D. degree work under the guidance of Prof. H.S. Misra at Molecular Biology Division, BARC, HBNI. I worked on genome partitioning system in bacteria which is a tripartite system with a centromere sequence, centromere binding protein (ParB) and motor NTPase ParA which recognize centromere-ParB complex and place the newly replicated genomic elements in daughter cells via their polymerization/depolymerization dynamics. D. radiodurans, a multipartite genome harboring bacteria with ploidy, contains 2 chromosomes (Chr I and Chr II) and 2 plasmids (megaplasmid; Mp and small plasmid; Sp). Each genomic replicon except small plasmid has own partitioning system. I worked on partitioning components of Chr II and Mp in comparison to Chr I. We approached to address the importance of multipartite genome in this organism. In addition, how segregation machinery cross-talk to cell division and replication machinery in this bacterium has been addressed. The summary of outcomes from my Ph.D. work is… Genome partitioning proteins of D. radiodurans interacts to core cell division proteins via. cell division regulatory proteins. We found that ParA proteins of Chr II and Mp (secondary genome) are functionally redundant and complement the function of each other in vivo. Secondary genome ParAs show both homotypic as well as hetrotypic interaction but did not interact with ParA1 (Chr I). ParA1 from Chr I did not complement the loss of ParAs from secondary genome suggesting the independent segregation mechanism for Chr I and secondary genome. The loss of parA2 (Chr II) and parA3 (Mp) together has decreased the ploidy of cognate genomic replicons and increased the sensitivity for abiotic stresses (γ-radiation and H2O2). Deinococcal ParBs form homodimer and interact to cognate ParA proteins in vivo. Deletion of parBs from each genomic replicon has increased the ploidy of cognate genomic replicons. Deletion of parB1 makes cells more sensitive to abiotic stresses than deletion of parB2 or parB3. ParAs and ParBs of D. radiodurans interaction DNA replication initiation proteins DnaA and DnaB in vivo suggesting an interdependent regulation of both processes. Direct repeats present near the origin and upstream to parAB operons in Chr II and Mp have the features of both origin of replication (it make suicidal plasmid replicative in vivo and showed a strong affinity with DnaA protein) and centromere (showed strong and specific interaction with cognate ParB proteins). We have generated functional Fluorescent Reporter Operator System (FROS) for D. radiodurans. In this, we have tagged different genomic replicons with GFP or RFP using tetO/TetR-GFP and lacO/LacI-RFP system. We monitored the location of each genomic replicons in vivo using fluorescence microscopy. We planned to monitor the dynamics of the genome during recovery from radiation and in different segregation or DNA repair mutant background. In parallel, I reported the role of phosphorylation of FtsA and FtsZ by a serine/threonine kinase (RqkA) in the regulation of cell division in D. radiodurans. I also worked on RecD and RecQ helicase and their role in G4 DNA metabolism. I have worked on replication initiation proteins (DnaA and DnaB) of D. radiodurans.
