General annotation (Comments)
| Function | AMP deaminase plays a critical role in energy metabolism. |
| Catalytic activity | AMP + H2O = IMP + NH3. |
| Pathway | Purine metabolism; IMP biosynthesis via salvage pathway; IMP from AMP: step 1/1. |
| Subunit structure | Homotetramer. |
| Tissue specificity | Three isoforms are present in mammals: AMP deaminase 1 is the predominant form in skeletal muscle; AMP deaminase 2 predominates in smooth muscle, non-muscle tissue, embryonic muscle and undifferentiated myoblasts; AMP deaminase 3 is found in erythrocytes. |
| Sequence similarities | Belongs to the adenosine and AMP deaminases family. |
