Protein existenceEvidence at protein level

General annotation (Comments)

Function

Involved in regulation of AMP concentrations.

Catalytic activity

AMP + H2O = D-ribose 5-phosphate + adenine.

Enzyme regulation

Allosterically activated by Mg-ATP, and inactivated by inorganic phosphate.

Pathway

Purine metabolism; AMP biosynthesis via salvage pathway; AMP from adenine: step 1/1.

Induction

By cAMP at limiting phosphate concentrations. Repressed by phosphate.

Miscellaneous

AMP nucleosidase binds AMP at the catalytic site, Mg-ATP at an allosteric regulatory site, and inorganic phosphate also at a regulatory site.
