Research Group: Dynamic Metabolons

• Structural organization
  We are studying the structural organization of metabolons and their different configurations. We are interested in general mechanisms regulating the assembly of metabolons such as scaffolding proteins, protein-protein interactions and the local membrane environment.

• Dynamic assembly
  We are uncovering the dynamics of metabolon assembly at the single molecule level. The diffusion of individual enzymes and entire metabolons provides kinetic insight on the assembly and disassembly. In the process, we are developing new platforms for studying protein-protein interactions, membrane sorting and binding of soluble enzymes.

• Functional consequences
  We apply our findings to study the functional consequences of enzyme engineering and lipid composition on substrate channeling using in vivo and in vitro systems. As part of this research topic we are optimizing biomimetic membrane systems for studying multienzyme complexes.

For students wishing to work within these topics. M.Sc. and B.Sc. projects are currently available. Please contact tola@plen.ku.dk

Our research group take an interdisciplinary basic science approach to elucidate fundamental mechanisms governing the plasticity of the biosynthesis of phytochemicals, which is well positioned between multiple groups at the Section for Plant biochemistry working on pathway discovery and heterologous production, including:

• Biochemical engineering (Sotirios Kampranis)
• Synthetic Biology (Birger Lindberg Møller)
• High-Value Phytochemicals (Irini Pateraki)
• Molecular Evolution of Specialized Metabolism (Søren Bak)

Our basic science approach benefits from collaboration with additional internal groups with expertise in plant physiology and metabolomics, including:

• Plant Ecophysiology (Elisabeth Heather Neilson)
• Plant Metabolic plasticity (Nanna Bjarnholt)

We are actively collaborating with world leading external experts, which provide access to state-of-the-art technologies and knowledge, including:
