Figure 4From: Cloning and characterization of Escherichia coli DUF299: a bifunctional ADP-dependent kinase - Pi-dependent pyrophosphorylase from bacteriaScheme for the regulation of E. coli PEPS by ADP, pyruvate and ATP. The phosphorylation status of the catalytically-important histidine residue (His) and the regulatory threonine (Thr) residue of PEPS is shown and the location of the ATP, ADP and pyruvate is highlighted in boxes.Back to article page
