Post-expression strategies for structural investigations of membrane proteins

Post-expression strategies for structural investigations of membrane proteins
Columbus, 2015 - COSB
  • Four techniques used to facilitate MP expression: 
    • limited proteolysis - removes flexible regions
    • Deglycosylation - removes heterogeneous post-translational modifications
    • cysteine alkylation - prevents disulfide dimers and higher order oligomers
    • lysine methylation 
  • Useful for determining more than 40 MP structures
