Name | Histamine N-methyltransferase |
| Function | Histamine N-methyltransferase (EC 2.1.1.8) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to histamine to form N(tau) methylhistamine and S-adenosyl-L-homocysteine. |
| Scope(s) |
Eukaryota Euteleostomi |
| Example(s) | Q5R7C3 (HNMT_PONAB); |
