putrescine biosynthetic process from arginine via N-carbamoylputrescine
putrescine biosynthetic process from arginine via n-carbamoylputrescine
The chemical reactions and pathways resulting in the formation of putrescine, 1,4-diaminobutane, from other compounds, including arginine, via the intermediate N-carbamoylputrescine; in this pathway, arginine is converted to agmatine, and agmatine is converted to putrescine in two single enzymatic steps.
