General annotation (Comments)

Function

Catalyzes the N-methylation of tryptamine and structurally related compounds By similarity. Functions as thioether S-methyltransferase and is active with a variety of thioethers and the corresponding selenium and tellurium compounds, including 3-methylthiopropionaldehyde, dimethyl selenide, dimethyl telluride, 2-methylthioethylamine, 2-methylthioethanol, methyl-n-propyl sulfide and diethyl sulfide. Plays an important role in the detoxification of selenium compounds By similarity.

Catalytic activity

S-adenosyl-L-methionine + an amine = S-adenosyl-L-homocysteine + a methylated amine.

S-adenosyl-L-methionine + dimethyl sulfide = S-adenosyl-L-homocysteine + trimethylsulfonium.

Subunit structure

Monomer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the class I-like SAM-binding methyltransferase superfamily. NNMT/PNMT/TEMT family.
