Abstract

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.
