Protein

Thyroid peroxidase

Gene

TPO

Organism
Sus scrofa (Pig)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Iodination and coupling of the hormonogenic tyrosines in thyroglobulin to yield the thyroid hormones T3 and T4.

Catalytic activityi

2 iodide + H2O2 + 2 H+ = 2 iodine + 2 H2O.
[Thyroglobulin]-L-tyrosine + iodide + H2O2 = [thyroglobulin]-3-iodo-L-tyrosine + 2 H2O.
[Thyroglobulin]-3-iodo-L-tyrosine + iodide + H2O2 = [thyroglobulin]-3,5-diiodo-L-tyrosine + 2 H2O.
2 [thyroglobulin]-3,5-diiodo-L-tyrosine + H2O2 = [thyroglobulin]-L-thyroxine + [thyroglobulin]-aminoacrylate + 2 H2O.
[Thyroglobulin]-3-iodo-L-tyrosine + [thyroglobulin]-3,5-diiodo-L-tyrosine + H2O2 = [thyroglobulin]-3,5,3'-triiodo-L-thyronine + [thyroglobulin]-aminoacrylate + 2 H2O.

Cofactori

Binds 1 calcium ion per heterodimer.PROSITE-ProRule annotation
Binds 1 heme B (iron-protoporphyrin IX) group covalently per heterodimer.PROSITE-ProRule annotation
