WebPhenylalanine Hydroxylse (PheOH) is an enzyme coded for by the PAHgene, found on human chromosome 12. PheOH is responsible for the conversion of the amino acid … WebPhenylalanine hydroxylase (PheOH) catalyzes the conversion of l-phenylalanine tol-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 …
