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.
