KEGG ENZYME: 1.21.99.3

ENZYME: 1.21.99.3

Entry

EC 1.21.99.3                Enzyme

Name

thyroxine 5-deiodinase;
diiodothyronine 5'-deiodinase (ambiguous);
iodothyronine 5-deiodinase;
iodothyronine inner ring monodeiodinase;
type III iodothyronine deiodinase

Class

Oxidoreductases;
Catalysing the reaction X-H + Y-H = X-Y;
With unknown physiological acceptors

Sysname

3,3',5'-triiodo-L-thyronine,iodide:acceptor oxidoreductase (iodinating)

Reaction(IUBMB)

3,3',5'-triiodo-L-thyronine + iodide + acceptor + H+ = L-thyroxine + reduced acceptor [RN:R07230]

Reaction(KEGG)

R07230

Substrate

3,3',5'-triiodo-L-thyronine [CPD:C07639];
iodide [CPD:C00708];
acceptor [CPD:C00028];
H+ [CPD:C00080]

Product

L-thyroxine [CPD:C01829];
reduced acceptor [CPD:C00030]

Comment

The enzyme activity has only been demonstrated in the direction of 5-deiodination. This removal of the 5-iodine, i.e. from the inner ring, largely inactivates the hormone thyroxine.

History

EC 1.21.99.3 created 2003 as EC 1.97.1.11, transferred 2015 to EC 1.21.99.3

Orthology

K07754
