Deiodinase (or iodide peroxidase or "Monodeiodinase") is a peroxidase enzyme that is involved in the activation or deactivation of thyroid hormones. In general, T4 (thyroxine) is converted into T3 (triiodothyronine) by the deiodinase enzyme in target cells.
Types of deiodinases include:
family prosthetic group genes Iodothyronine deiodinase selenium DIO1, DIO2, DIO3 Iodotyrosine deiodinase flavin IYD Oxidoreductases: peroxidases (EC 1.11) 184.108.40.206-14 220.127.116.11 (peroxiredoxin) B enzm: 1.1/2/3/4/5/6/7/8/10/11/13/14/15-18, 2.1/2/3/4/5/6/7/8, 2.7.10, 2.7.11-12, 3.1/2/3/4/5/6/7, 18.104.22.168, 3.4.21/22/23/24, 4.1/2/3/4/5/6, 5.1/2/3/4/99, 6.1-3/4/5-6 This enzyme-related article is a stub.
