STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

pucIAllantoin permease; Transport of allantoin. (490 aa)    
Predicted Functional Partners:
pucH
Allantoinase; Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoic acid by hydrolytic cleavage of the five-member hydantoin ring.
 
  
 0.977
pucF
Allantoate amidohydrolase; Involved in the anaerobic nitrogen utilization via the assimilation of allantoin. Catalyzes specifically the hydrolysis of allantoate to yield CO2, NH3 and S-ureidoglycine, which is unstable and readily undergoes a second deamination by S- ureidoglycine aminohydrolase AllE to yield S-ureidoglycolate and NH3 (By similarity).
 
  
 0.967
pucM
5-hydroxyisourate hydrolase; Catalyzes the hydrolysis of 5-hydroxyisourate (HIU) to 2-oxo- 4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU).
 
  
 0.957
pucJ
Uric acid permease; Uptake of uric acid.
 
  
 0.950
pucR
Transcriptional regulator of the purine degradation operon; Activates the expression of pucFG, pucH, pucI, pucJKLM and guaD, while it represses pucABCDE and its own expression. Belongs to the CdaR family.
 
  
 0.942
pucL
Urate oxidase with peroxide reductase N-terminal domain; Catalyzes two steps in the degradation of uric acid, i.e. the oxidation of uric acid to 5-hydroxyisourate (HIU) and the stereoselective decarboxylation of 2-oxo-4-hydroxy-4-carboxy-5- ureidoimidazoline (OHCU) to (S)-allantoin.
 
  
 0.935
pucE
Xanthine dehydrogenase, iron-sulfur subunit; Oxidizes hypoxanthine and xanthine to uric acid.
   
  
 0.917
pucC
Xanthine dehydrogenase, FAD-binding subunit; Oxidizes hypoxanthine and xanthine to uric acid.
  
  
 0.915
guaD
Guanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia.
 
   
 0.910
pucD
Xanthine dehydrogenase, substrate and molybdenum cofactor subunit; Oxidizes hypoxanthine and xanthine to uric acid. Belongs to the xanthine dehydrogenase family.
   
  
 0.909
