Structural Genomics

  • Optimization of gene expression and identification of bottlenecks in protein production. Lactococcus lactis and Escherichia coli are used as hosts for the overexpression of membrane proteins.1,2 A high-throughput method for cloning in E.coli and L. lactis is available. Expression screening by GFP-tagging of proteins is shown in the picture.
  • Hydrodynamic analysis of proteins: analytical ultracentrifugation and multi-angle light scattering-coupled to size-exclusion chromatography are used to determine oligomeric state and monodispersity of membrane proteins.
  • Crystallography: in collaboration with the group of Andy-Mark Thunnissen and Bauke Dijkstra, X-ray crystallography is used to determine high-resolution structures of membrane proteins.
