Protein

ADP-ribose pyrophosphatase

Gene

nudF

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Acts on ADP-mannose and ADP-glucose as well as ADP-ribose. Prevents glycogen biosynthesis. The reaction catalyzed by this enzyme is a limiting step of the gluconeogenic process.1 Publication

Catalytic activityi

ADP-D-ribose + H2O = AMP + D-ribose 5-phosphate.1 Publication

Cofactori

Mg2+2 PublicationsNote: Binds 3 Mg2+ ions per subunit.2 Publications

Enzyme regulationi

Inhibited by phosphorylated compounds such as AMP, ADP, ATP, 3-phosphoglyceric acid and PPi. Not inhibited by orthophosphate. Activity is high in cells grown in low glucose concentrations and decreases dramatically as glucose concentration increases.
