Protein

Hypoxanthine phosphoribosyltransferase

Gene

hpt

Organism
Shigella flexneri
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

Acts preferentially on hypoxanthine; has very low activity towards guanine. Inactive towards xanthine (By similarity).By similarity

Catalytic activityi

IMP + diphosphate = hypoxanthine + 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
