Plays a crucial role in the metabolism of thyroid hormones (TH) and has specific roles in TH activation and inactivation by deiodination. Catalyzes the deiodination of L-thyroxine (T4) to 3,3',5'-triiodothyronine (rT3), 3,5-diiodothyronine (3,5-T2) to 3-monoiodothyronine (3-T1), rT3 to 3',5'-diiodothyronine (3',5'-T2) and 3,3'-diiodothyronine (3,3'-T2) to 3'-monoiodothyronine (3'-T1) via inner-ring deiodination (IRD) (By similarity). Catalyzes the deiodination of 3,5,3'-triiodothyronine (T3) to 3,3'-diiodothyronine (3,3'-T2) via IRD (PubMed:8052658). Catalyzes the deiodination of 3-T1 to L-thyronine (T0) via outer-ring deiodination (ORD) (By similarity). Catalyzes the tyrosyl ring deiodinations of 3,3',5,5'-tetraiodothyronamine, 3,3',5'-triiodothyronamine, 3,5,3'-triiodothyronamine, 3,5-diiodothyronamine, 3,3'-diiodothyronamine and 3-iodothyronamine (By similarity).; Thyroxine 5-deiodinase [-]
