Taxonomic identifier

367830 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Staphylococcus

Protein attributes

Sequence length	325 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 + NH(3) + NADP(+) = guanosine 5'-phosphate + NADPH.
Sequence similarities	Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
