• 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
