TETRAMERIC HUMAN PHENYLALANINE HYDROXYLASE
Overview
Phenylalanine hydroxylase (PheOH) catalyzes the conversion of, L-phenylalanine to L-tyrosine, the rate-limiting step in the oxidative, degradation of phenylalanine. Mutations in the human PheOH gene cause, phenylketonuria, a common autosomal recessive metabolic disorder that in, untreated patients often results in varying degrees of mental retardation., We have determined the crystal structure of human PheOH (residues, 118-452). The enzyme crystallizes as a tetramer with each monomer, consisting of a catalytic and a tetramerization domain. The, tetramerization domain is characterized by the presence of a domain, swapping arm that interacts with the other monomers forming an, antiparallel coiled-coil. The structure is the first report of a, tetrameric PheOH and displays an overall ... [(full description)]
