- S-adenosyl-L-methionine + (S)-7,8,13,14-tetrahydroprotoberberine S-adenosyl-L-homocysteine + cis-N-methyl-(S)-7,8,13,14-tetrahydroprotoberberine
Thus, the two substrates of this enzyme are S-adenosyl methionine and (S)-7,8,13,14-tetrahydroprotoberberine, whereas its two products are S-adenosylhomocysteine and cis-N-methyl-(S)-7,8,13,14-tetrahydroprotoberberine.
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:(S)-7,8,13,14-tetrahydroprotoberberine cis-N-methyltransferase. This enzyme is also called tetrahydroprotoberberine cis-N-methyltransferase. This enzyme participates in alkaloid biosynthesis i.
