Taxonomic identifier

1423 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Bacillaceae › Bacillus

Protein attributes

Sequence length	326 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

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 Probable. Ref.4
Catalytic activity	Inosine 5'-phosphate + NH3 + NADP+ = guanosine 5'-phosphate + NADPH. HAMAP MF_01511
Induction	Expression is regulated by PurR. Ref.4
Sequence similarities	Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
