Short name=Guanosine monophosphate reductase
Gene names
Name:guaC
Ordered Locus Names:Exig_1681
OrganismExiguobacterium sibiricum (strain DSM 17290 / JCM 13490 / 255-15) [Complete proteome] [HAMAP]
Taxonomic identifier262543 [NCBI]
Taxonomic lineageBacteria › Firmicutes › Bacillales › Bacillales Family XII. Incertae Sedis › Exiguobacterium

Protein attributes

Sequence length328 AA.
Sequence statusComplete.
Protein existenceInferred 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. HAMAP MF_01511

Catalytic activity

Inosine 5'-phosphate + NH3 + NADP+ = guanosine 5'-phosphate + NADPH. HAMAP MF_01511

Sequence similarities

Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
