Research Interests

Our research group investigates the fundamental question of how proteins are synthesized, folded and assembled into functional multicomponent bioenergetic complexes that drive the cellular energy production.

Living cells ultimately depend on the conversion of energy derived from foodstuff and light into the chemical form of energy. This crucial bioenergetic step is performed in the membrane systems of mitochondria and chloroplasts. Each one of these organelle types has developed dedicated gene expression and assembly machineries that have diverged from the cytosolic counterparts. While mitoribosomes synthesize proteins involved in the oxidative phosphorylation, chlororibosomes produce components driving the photosynthetic reactions through pigment-protein units. To dissect the mechanism and dynamics of how the bioenergetic units that fuel life become to be, the lab members employ structural, functional and evolutionary analysis.

The lab has determined the molecular mechanisms of some of the most complex multi protein assemblies driving key bioenergetic processes, including chlororibosomes, mitoribosomes, photosystems and ATP synthases. The revealed activities and regulation illuminate how different cells obtain their energy and maintain the bioenergetic balance. From the evolutionary perspective, the achieved understanding of the architecture of these specialized systems provides now a framework to study the mechanisms underlying the development of bioenergetic membranes.

The research is supported by the ERC, Wallenberg Foundation, SSF Future Leaders, EMBO Young Investigators, Cancer Foundation Junior Investigator Award.
