Reaction(IUBMB)
(1) 2 iodide + H2O2 + 2 H+ = diiodine + 2 H2O [RN:R02810];
(2) [thyroglobulin]-L-tyrosine + iodide + H2O2 = [thyroglobulin]-3-iodo-L-tyrosine + 2 H2O;
(3) [thyroglobulin]-3-iodo-L-tyrosine + iodide + H2O2 = [thyroglobulin]-3,5-diiodo-L-tyrosine + 2 H2O;
(4) 2 [thyroglobulin]-3,5-diiodo-L-tyrosine + H2O2 = [thyroglobulin]-L-thyroxine + [thyroglobulin]-aminoacrylate + 2 H2O [RN:R08523];
(5) [thyroglobulin]-3-iodo-L-tyrosine + [thyroglobulin]-3,5-diiodo-L-tyrosine + H2O2 = [thyroglobulin]-3,5,3'-triiodo-L-thyronine + [thyroglobulin]-aminoacrylate + 2 H2O [RN:R08522]

(other) R03208 R03539 R03953 R03973 R08520 R08521
Substrate
iodide [CPD:C00708];
H2O2 [CPD:C00027];
H+ [CPD:C00080];
[thyroglobulin]-L-tyrosine [CPD:C16733];
[thyroglobulin]-3-iodo-L-tyrosine [CPD:C16732];
[thyroglobulin]-3,5-diiodo-L-tyrosine [CPD:C16731]
Product
diiodine [CPD:C01382];
H2O [CPD:C00001];
[thyroglobulin]-3-iodo-L-tyrosine [CPD:C16732];
[thyroglobulin]-3,5-diiodo-L-tyrosine [CPD:C16731];
[thyroglobulin]-L-thyroxine [CPD:C16729];
[thyroglobulin]-aminoacrylate [CPD:C16734];
[thyroglobulin]-3,5,3'-triiodo-L-thyronine [CPD:C16730]
Comment
Thyroid peroxidase catalyses the biosynthesis of the thyroid hormones L-thyroxine and triiodo-L-thyronine. It catalyses both the iodination of tyrosine residues in thyroglobulin (forming mono- and di-iodinated forms) and their coupling to form either L-thyroxine or triiodo-L-thyronine.
