Fig. 6. Biophysical and biochemical properties of wild-type and mutant Hrs FYVE domains. The
-helical content (in millidegrees) of GST-fusions of wild-type and mutant FYVE domains was studied by CD spectroscopy (A), and the binding of GST-HrsFYVE and GST-HrsFYVER183A to PtdIns(3)P was analysed by surface plasmon resonance (B), as described in Materials and Methods. RU, resonance units.
