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. Ref.4

Catalytic activity

S-adenosyl-L-methionine + an amine = S-adenosyl-L-homocysteine + a methylated amine. Ref.4

S-adenosyl-L-methionine + dimethyl sulfide = S-adenosyl-L-homocysteine + trimethylsulfonium. Ref.4

Enzyme regulation

Inhibited by the S-adenosyl-L-methionine analog sinefungin and by the product S-adenosyl-L-homocysteine. Ref.4

Subunit structure

Monomer. Ref.4

Subcellular location

Cytoplasm Ref.4.

Tissue specificity

Detected in lung and liver (at protein level). Ref.4

Sequence similarities

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

Caution

Was originally (Ref.1) thought to be a thioether S-methyltransferase but appears to be the ortholog of human INMT.

Biophysicochemical properties

Kinetic parameters:

KM=0.4 µM for dimethyl selenide

KM=1.0 µM for dimethyl sulfide

KM=1.0 µM for S-adenosyl-L-methionine

pH dependence:

Optimum pH is 6.3.
