In enzymology, a [cytochrome c]-lysine N-methyltransferase (EC 2.1.1.59) is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + [cytochrome c]-L-lysine $\rightleftharpoons$ S-adenosyl-L-homocysteine + [cytochrome c]-N₆-methyl-L-lysine

Thus, the two substrates of this enzyme are S-adenosyl methionine and cytochrome c-L-lysine, whereas its two products are S-adenosylhomocysteine and cytochrome c-N6-methyl-L-lysine.

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:[cytochrome c]-L-lysine N6-methyltransferase. Other names in common use include cytochrome c (lysine) methyltransferase, cytochrome c methyltransferase, cytochrome c-specific protein methylase III, cytochrome c-specific protein-lysine methyltransferase, S-adenosyl-L-methionine:[cytochrome c]-L-lysine, and 6-N-methyltransferase. This enzyme participates in lysine degradation.
