Pyridine N-methyltransferase (EC 2.1.1.87) is an enzyme that catalyzes the chemical reaction

  1. REDIRECT Template:Chemical reaction

This is a methylation reaction in which pyridine is converted to methylpyridinium cation. The methyl group comes from the cofactor, S-adenosyl methionine (SAM), which becomes S-adenosyl-L-homocysteine (SAH).[1]

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:pyridine N-methyltransferase. This enzyme is also called pyridine methyltransferase.[2]
