Short name=HGPRT
Short name=HGPRTase
EC=2.4.2.8
Gene names
Name:hpt
Ordered Locus Names:SAR0511
OrganismStaphylococcus aureus (strain MRSA252) [Complete proteome] [HAMAP]
Taxonomic identifier282458 [NCBI]
Taxonomic lineageBacteriaFirmicutesBacilliBacillalesStaphylococcus

Protein attributes

Sequence length179 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

IMP + diphosphate = hypoxanthine + 5-phospho-alpha-D-ribose 1-diphosphate.

GMP + diphosphate = guanine + 5-phospho-alpha-D-ribose 1-diphosphate.

Cofactor

Binds 2 magnesium ions per subunit. The magnesium ions are essentially bound to the substrate and have few direct interactions with the protein By similarity.

Pathway

Purine metabolism; IMP biosynthesis via salvage pathway; IMP from hypoxanthine: step 1/1.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the purine/pyrimidine phosphoribosyltransferase family.
