This study explores the intricate metabolic pathways involving ornithine, UMP, ATP, CTP, and key enzymes such as GLNase, CPS-A, CPS-B, ATCase, and DHOase in two model organisms: Escherichia coli and Saccharomyces cerevisiae. We analyze how these pathways differ in mammals versus these microorganisms, highlighting regulatory mechanisms and enzyme interactions. The roles of various metabolites are examined, revealing insights into biosynthesis and energy metabolism. Our findings contribute to the understanding of metabolic regulation in diverse biological systems.
