Beschreibung

Allgemeine Beschreibung

Iodotyrosine coupled with di-iodotyrosine results in the synthesis of 3,5,3′-tri-iodothyronine (T3) or 3,3′,5′-tri-iodothyronine (rT3).

Anwendung

3-Iodo-L-tyrosine has been used as an inhibitor for tyrosine hydroxylase enzyme in Drosophila and silkworm pupae.

Biochem./physiol. Wirkung

3-iodotyrosine (3-IY) inhibits tyrosine hydroxylase that catalyzes levodopa (L-DOPA) formation from tyrosine. Iodotyrosine deiodinase enzyme deficiency leads to elevated levels of 3-IY in serum and urine in severe hypothyroidism and goiter.

TH (tyrosine 3-hydroxylase) is responsible for catalyzing the first step of the noradrenergic biosynthesis pathway. Mutations in TH are associated with tyrosine hydroxylase deficiency, leading to conditions such as infantile parkinsonism and DOPA (dopamine)-responsive dystonia as well as encephalopathy with perinatal onset.
