Hydrolysis from the imine derives N-carbamoylputrescine followed with hydrolysis with the urea to form putrescine. The separate pathways of converting ornithine to putrescine in vegetation and animals have converged. A SAM-dependent N-methylation of putrescine gives the N-methylputrescine item, which then undergoes oxidative deamination because of the action of diamine oxidase https://ammonn430tld1.blog-eye.com/profile
