Taxonomic identifier

272622 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Lactobacillales › Streptococcaceae › Lactococcus

Protein attributes

Sequence length	329 AA.
Sequence status	Complete.
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. 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.
