Evolution of the key alkaloid enzyme putrescine N-methyltransferase from spermidine synthase.

Evolution of the key alkaloid enzyme putrescine N-methyltransferase from spermidine synthase.

Putrescine N-methyltransferases (PMTs) are the first specific enzymes of the biosynthesis of nicotine and tropane alkaloids. PMTs transfer a methyl group onto the diamine putrescine from S-adenosyl-L-methionine (SAM) as coenzyme. PMT proteins have presumably evolved from spermidine synthases (SPDSs)...
