Protein

Hypoxanthine-guanine phosphoribosyltransferase

Gene

hpt

Organism
Rhodobacter capsulatus (strain ATCC BAA-309 / NBRC 16581 / SB1003)
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

Mg2+By similarityNote: 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
