Noun
a colorless crystalline ptomaine with a foul odor that is produced in decaying animal matter
Source: WordNetA 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. Source: Internet
Hydrolysis of the imine derives N-carbamoylputrescine followed with hydrolysis of the urea to form putrescine. Source: Internet
In animals, however, the urea cycle derives putrescine from ornithine. Source: Internet
Putrescine is then converted into N-methyl putrescine via methylation by SAM catalyzed by putrescine N-methyltransferase (PMT). Source: Internet
The separate pathways of converting ornithine to putrescine in plants and animals have converged. Source: Internet
