In enzymology, a (RS)-1-benzyl-1,2,3,4-tetrahydroisoquinoline N-methyltransferase is an enzyme that catalyzes the chemical reaction:[1]
- S-adenosyl-L-methionine + (RS)-1-benzyl-1,2,3,4-tetrahydroisoquinoline S-adenosyl-L-homocysteine + N-methyl-(RS)-1-benzyl-1,2,3,4-tetrahydroisoquinoline
This enzyme participates in alkaloid biosynthesis.
Nomenclature
[edit]This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:(RS)-1-benzyl-1,2,3,4-tetrahydroisoquinoline N-methyltransferase. This enzyme is also called norreticuline N-methyltransferase.
