| phenylalanine 4-monooxygenase | The active centre contains mononuclear iron(II). The reaction involves an arene oxide that rearranges to give the phenolic hydroxy group. This results in the hydrogen at C-4 migrating to C-3 and in part being retained. This process is known as the NIH-shift. The 4a-hydroxytetrahydrobiopterin formed can dehydrate to 6,7-dihydrobiopterin, both spontaneously and by the action of EC 4.2.1.96, 4a-hydroxytetrahydrobiopterin dehydratase. The 6,7-dihydrobiopterin can be enzymically reduced back to tetrahydrobiopterin, by EC 1.5.1.34, 6,7-dihydropteridine reductase, or slowly rearranges into the more stable compound 7,8-dihydrobiopterin. Group: Enzymes. Synonyms: phenylalaninase; phenylalanine 4-hydroxylase; phenylalanine hydroxylase. Enzyme Commission Number: EC 1.14.16.1. CAS No. 9029-73-6. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0953; phenylalanine 4-monooxygenase; EC 1.14.16.1; 9029-73-6; phenylalaninase; phenylalanine 4-hydroxylase; phenylalanine hydroxylase. Cat No: EXWM-0953. | |
| tryptophan 5-monooxygenase | The active centre contains mononuclear iron(II). The enzyme is activated by phosphorylation, catalysed by a Ca2+-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, 4a-hydroxytetrahydrobiopterin dehydratase. The 6,7-dihydrobiopterin can be enzymically reduced back to tetrahydrobiopterin, by EC 1.5.1.34 (6,7-dihydropteridine reductase), or slowly rearranges into the more stable compound 7,8-dihydrobiopterin. Group: Enzymes. Synonyms: L-tryptophan hydroxylase; indoleacetic acid-5-hydroxylase; tryptophan 5-hydroxylase; tryptophan hydroxylase. Enzyme Commission Number: EC 1.14.16.4. CAS No. 9037-21-2. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0956; tryptophan 5-monooxygenase; EC 1.14.16.4; 9037-21-2; L-tryptophan hydroxylase; indoleacetic acid-5-hydroxylase; tryptophan 5-hydroxylase; tryptophan hydroxylase. Cat No: EXWM-0956. | |
| tyrosine 3-monooxygenase | The active centre contains mononuclear iron(II). The enzyme is activated by phosphorylation, catalysed by EC 2.7.11.27, [acetyl-CoA carboxylase] kinase. The 4a-hydroxytetrahydrobiopterin formed can dehydrate to 6,7-dihydrobiopterin, both spontaneously and by the action of EC 4.2.1.96, 4a-hydroxytetrahydrobiopterin dehydratase. The 6,7-dihydrobiopterin can be enzymically reduced back to tetrahydrobiopterin, by EC 1.5.1.34 (6,7-dihydropteridine reductase), or slowly rearranges into the more stable compound 7,8-dihydrobiopterin. Group: Enzymes. Synonyms: L-tyrosine hydroxylase; tyrosine 3-hydroxylase; tyrosine hydroxylase. Enzyme Commission Number: EC 1.14.16.2. CAS No. 9036-22-0. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0954; tyrosine 3-monooxygenase; EC 1.14.16.2; 9036-22-0; L-tyrosine hydroxylase; tyrosine 3-hydroxylase; tyrosine hydroxylase. Cat No: EXWM-0954. | |
