A SAM-dependent N-methylation of putrescine gives the N-methylputrescine product, which then undergoes oxidative deamination by the action of diamine oxidase to yield the aminoaldehyde.
Hydrolysis of the imine derives N-carbamoylputrescine followed with hydrolysis of the urea to form putrescine.
In animals, however, the urea cycle derives putrescine from ornithine.
Putrescine is then converted into N-methyl putrescine via methylation by SAM catalyzed by putrescine N-methyltransferase (PMT).
The separate pathways of converting ornithine to putrescine in plants and animals have converged.
