| Accepted name: |
thyroid-hormone transaminase |
| Reaction: |

| Other name(s): |
3,5-dinitrotyrosine transaminase; thyroid hormone aminotransferase |
| Systematic name: |
L-3,5,3′-triiodothyronine:2-oxoglutarate aminotransferase |
| Comments: |
A pyridoxal-phosphate protein. Acts on monoiodotyrosine, diiodotyrosine, triiodothyronine, thyroxine and dinitrotyrosine (unlike EC 2.6.1.24 diiodotyrosine transaminase, which does not act on dinitrotyrosine). Pyruvate or oxaloacetate can act as acceptors. |
