iodide peroxidase activity
Catalysis of the reactions: (1) 2 iodide + H2O2 + 2 H+ = diiodine + 2 H2O; (2) [thyroglobulin]-L-tyrosine + iodide + H2O2 + H+ = [thyroglobulin]-3-iodo-L-tyrosine + 2 H2O; (3) [thyroglobulin]-3-iodo-L-tyrosine + iodide + H2O2 + H+ = [thyroglobulin]-3,5-diiodo-L-tyrosine + 2 H2O; (4) 2 [thyroglobulin]-3,5-diiodo-L-tyrosine + H2O2 = [thyroglobulin]-L-thyroxine + [thyroglobulin]-dehydroalanine + 2 H2O; (5) [thyroglobulin]-3-iodo-L-tyrosine + [thyroglobulin]-3,5-diiodo-L-tyrosine + H2O2 = [thyroglobulin]-3,3',5-triiodo-L-thyronine + [thyroglobulin]-dehydroalanine + 2 H2O.
