| Hexavalent chromium can inhibit benzpyrene hydroxylase activity. |
| Phenylalanine is normally converted in the human body to tyrosine, another amino acid, by a specific organic catalyst, or enzyme, called phenylalanine hydroxylase. |
| Induction of increased benzpyrene hydroxylase activity by flavones and related compounds. |
| Prolyl 4-hydroxylase and lysyl hydroxylase are known also to catalyze an uncoupled decarboxylation of 2-oxoglutarate in the absence of the peptide substrate. |
| Influence of methamphetamine on nigral and striatal tyrosine hydroxylase activity and on striatal dopamine levels. |
| Betacynin biosynthesis starts by the oxidation of tyrosine to dopa by a tyrosine hydroxylase. |
