Protein attributes
| Sequence length | 347 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Inferred from homology. |
General annotation (Comments)
| Function | Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides By similarity. |
| Catalytic activity | Inosine 5'-phosphate + NH3 + NADP+ = guanosine 5'-phosphate + NADPH. HAMAP MF_00596 |
| Subunit structure | Homotetramer By similarity. |
| Sequence similarities | Belongs to the IMPDH/GMPR family. GuaC type 1 subfamily. |
