Morth Group: Structural Facilities

A variety of techniques are used in order to identify, and characterise, both soluble and membrane bound proteins involved in metal/pH regulation.

  • Structural modelling and bioinformatics approach are used to target new proteins and interaction partners of interest.
  • A broad cloning strategy in both yeast and bacterial expression systems is employed to search for membrane/soluble proteins.
  • Protocols for the purification and reconstitution of lipid vesicle for membrane proteins (Subramani, Perdreau-Dahl, and Morth, 2016)
  • Structural information is obtained by X-ray crystallography, small angle X-ray scattering (SAXS) and small angle neutron scattering (SANS).

Several biophysical and biochemical techniques are also used:

  • Fluorescent binding assays, including drug screening (Gerner, Munack, et al, 2016a; Gerner, Munack, et al, 2016b)
  •  Differential scanning fluorimetry (DSF), for melting point, folding and stability measures (Leo, Oberhettinger, et al, 2016)
  • Anisotropic fluorescence measurement, stop flow
  • Spectroscopic activity assays and enzyme kinetics (Bjerregaard-Andersen, Sommer, et al, 2014; Sommer, Bjerregaard-Andersen, et al, 2015; Subramani, Perdreau-Dahl, and Morth, 2016).
