Protein
Hypoxanthine-guanine phosphoribosyltransferase
Gene
hpt, MPN_672, MP170
Organism
Mycoplasma pneumoniae (strain ATCC 29342 / M129)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Catalytic activityi

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

Cofactori

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.
