Tyrosine hydroxylase deficiency; Simplified overview of the biosynthesis and catabolism of serotonin and the catecholamines, with tyrosine hydroxylase (TH) and its cofactor tetrahydrobiopterin (BH 4) circled in red. Note that different parts of these processes take place in different tissues.
In humans, tyrosinase is sorted into melanosomes [13] and the catalytically active domain of the protein resides within melanosomes. Only a small, enzymatically inessential part of the protein extends into the cytoplasm of the melanocyte. As opposed to fungal tyrosinase, human tyrosinase is a membrane-bound glycoprotein and has 13% carbohydrate ...
Tyrosine hydroxylase or tyrosine 3-monooxygenase is the enzyme responsible for catalyzing the conversion of the amino acid L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA). [5] [6] It does so using molecular oxygen (O 2), as well as iron (Fe 2+) and tetrahydrobiopterin as cofactors.
