  • PubMed Abstract: 
  • Not without a chaperone: Pharmacological chaperones are designed to bind and ideally stabilise their target protein. Here, we elucidate the molecular mechanism of a potential pharmacological chaperone to treat phenylketonuria. The crystal structure of human phenylalanine hydroxylase with compound IV may help in the rational design of more efficient compounds to treat this disease ...
