the catalytic cycle of ID-1 involves a ping-pong bisubstrate reaction in which the selenol form of the enzyme (ESeH) reacts with L-thyroxine to form a selenenyl iodide intermediate (ESeI) with release of the deiodinated compound 3,5,3'-triiodo-L-thyronine, and a subsequent reaction between the selenenyl iodide intermediate and possibly a thiol cofactor regenerates the selenol form

thyronines and thyronamines are two groups of endogenous iodine-containing signaling molecules that are substrates of three deiodinase isozymes, which catalyze the sequential reductive removal of iodine from the respective precursor molecule.
