putrescine biosynthetic process from arginine, using agmatinase
"The chemical reactions and pathways resulting in the formation of putrescine, 1,4-diaminobutane, from other compounds, including arginine; in this pathway, arginine is converted to agmatine, and agmatine is converted to putrescine in a single enzymatic step."
