RESEARCH OVERVIEW
We study Actinobacteria (Streptomyces, Mycobacteria), focusing on:
- chromosome organization during the cell cycle, including the roles of topoisomerases, nucleoid-associated proteins, and condensins;
- chromosome replication and its regulation by chromosome topology;
- mechanisms of chromosome segregation, particularly the role of the ParAB system;
- coordination of the cell cycle, including the synchronization of chromosome segregation with cell division and cell elongation;
- regulation of gene expression, emphasizing the influence of chromosome topology and transcriptional regulators;
- morphogenesis and apical cell growth;
- antibiotic biosynthesis and the activation of silent biosynthetic pathways.
