  • 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.
