Scientific Background : Uridylate kinase, also known as UMP kinase, in E. coli catalyze the phosphorylation of UMP and ATP to yield UDP and ADP with Mg²⁺ as the cofactor (1). Bacterial UMP kinases are hexamers and are allosterically activated by GTP and allosterically inhibited by UTP (1,2). They are the most studied nucleoside monophosphate (NMP) kinase in their family and have sequence similarity to aspartokinases, glutamate kinases, and Pseudomonas aeruginosa carbamate kinase (2). UMP kinase is a regulatory enzyme in the de novo biosynthetic pathway of pyrimidine molecules (3).
