Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the oxidation of uric acid to 5-hydroxyisourate, which is further processed to form (S)-allantoin.1 Publication

Catalytic activityi

Urate + O2 + H2O = 5-hydroxyisourate + H2O2.1 Publication

Enzyme regulationi

Competitively inhibited by xanthine.1 Publication

Kineticsi

  1. KM=8.33 µM for urate1 Publication

    Pathwayi: urate degradation

    This protein is involved in step 1 of the subpathway that synthesizes (S)-allantoin from urate.1 Publication
    Proteins known to be involved in the 3 steps of the subpathway in this organism are:
    1. Uricase (Uox)
    2. no protein annotated in this organism
    3. no protein annotated in this organism
    This subpathway is part of the pathway urate degradation, which is itself part of Purine metabolism.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes (S)-allantoin from urate, the pathway urate degradation and in Purine metabolism.
