A chemical model for the inner-ring deiodination of thyroxine by iodothyronine deiodinase

Manna, Debasish,Mugesh, Govindasamy

body text, p. 9246 - 9249 (2011/02/22)

The I of the beholder: The presented chemical model for the inner-ring deiodination of thyroxine (T4) and 3,5,3′-triiodothyronine (T3) by iodothyronine deiodinase (see scheme) highlights the importance of an in-built thiol group in proximity to the selenium atom. The effective removal of iodine in the case of T4 indicates that an enol-keto tautomerism is not required for deiodination. Copyright
