Hydrolysis of the imine derives N-carbamoylputrescine followed with hydrolysis in the urea to variety putrescine. The separate pathways of changing ornithine to putrescine in crops and animals have converged. A SAM-dependent N-methylation of putrescine gives the N-methylputrescine item, which then undergoes oxidative deamination because of the motion of diamine oxidase https://arthure784uhr4.lotrlegendswiki.com/user
