Protein

5-hydroxyisourate hydrolase

Gene

pucM

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the hydrolysis of 5-hydroxyisourate (HIU) to 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU).

Catalytic activityi

5-hydroxyisourate + H2O = 5-hydroxy-2-oxo-4-ureido-2,5-dihydro-1H-imidazole-5-carboxylate.1 Publication

Pathwayi: urate degradation

This protein is involved in step 2 of the subpathway that synthesizes (S)-allantoin from urate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Uric acid degradation bifunctional protein PucL (pucL)
  2. 5-hydroxyisourate hydrolase (pucM)
  3. Uric acid degradation bifunctional protein PucL (pucL)
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.

Expressioni

Inductioni

Expression is very low in excess nitrogen (glutamate plus ammonia) and is induced by TnrA during limiting-nitrogen conditions (glutamate). Expression is further induced when allantoin or uric acid are added during limiting-nitrogen conditions.2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
