Enzyme Information
1.14.16.4 |
Tryptophan 5-monooxygenase.
based on mapping to UniProt P17752
L-tryptophan + tetrahydrobiopterin + O(2) = 5-hydroxy-L-tryptophan + 4a-hydroxytetrahydrobiopterin.
-!- Activated by phosphorylation, catalyzed by a Ca(2+)-activated protein kinase. -!- The 4a-hydroxytetrahydrobiopterin formed can dehydrate to 6,7- dihydrobiopterin, both spontaneously and by the action of EC 4.2.1.96. -!- The 6,7-dihydrobiopterin can be enzymically reduced back to tetrahydrobiopterin, by EC 1.5.1.34, or slowly rearranges into the more stable compound 7,8-dihydrobiopterin.
