Hydrolysis with the imine derives N-carbamoylputrescine followed with hydrolysis from the urea to kind putrescine. The separate pathways of converting ornithine to putrescine in vegetation and animals have converged. A SAM-dependent N-methylation of putrescine presents the N-methylputrescine merchandise, which then undergoes oxidative deamination because of the motion of diamine oxidase https://frankk741bzx7.plpwiki.com/user
