Protein

Histamine N-methyltransferase

Gene

hnmt

Organism
Tetraodon nigroviridis (Spotted green pufferfish) (Chelonodon nigroviridis)
Status
Reviewed - Annotation score: 2 out of 5- Protein inferred from homologyi

Functioni

Inactivates histamine by N-methylation. Plays an important role in degrading histamine and in regulating the airway response to histamine (By similarity).By similarity

Catalytic activityi

S-adenosyl-L-methionine + histamine = S-adenosyl-L-homocysteine + N(tau)-methylhistamine.PROSITE-ProRule annotation
