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

hiuHHydroxyisourate hydrolase; Catalyzes the hydrolysis of 5-hydroxyisourate (HIU) to 2-oxo- 4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU). (137 aa)    
Predicted Functional Partners:
yedZ
Inner membrane heme subunit for periplasmic YedYZ reductase; Part of the MsrPQ system that repairs oxidized periplasmic proteins containing methionine sulfoxide residues (Met-O), using respiratory chain electrons. Thus protects these proteins from oxidative-stress damage caused by reactive species of oxygen and chlorine. MsrPQ is essential for the maintenance of envelope integrity under bleach stress, rescuing a wide series of structurally unrelated periplasmic proteins from methionine oxidation, including the primary periplasmic chaperone SurA and the lipoprotein Pal. MsrQ provides el [...]

yedY
Membrane-anchored, periplasmic TMAO, DMSO reductase; Part of the MsrPQ system that repairs oxidized periplasmic proteins containing methionine sulfoxide residues (Met-O), using respiratory chain electrons. Thus protects these proteins from oxidative-stress damage caused by reactive species of oxygen and chlorine. MsrPQ is essential for the maintenance of envelope integrity under bleach stress, rescuing a wide series of structurally unrelated periplasmic proteins from methionine oxidation, including the primary periplasmic chaperone SurA and the lipoprotein Pal. The catalytic subunit Ms [...]

yedW
Response regulator family protein; Member of a two-component regulatory system HprR/HprS involved in response to hydrogen peroxide. Regulates the expression of at least 5 operons, cyoABCDE, hprRS, hiuH, cusRS and cusCFBA. Bifunctional regulator that acts as an activator and a repressor.
  
  
 0.776
guaD
Guanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family.
 
   
 0.771
allA
Ureidoglycolate lyase, releasing urea; Catalyzes the catabolism of the allantoin degradation intermediate (S)-ureidoglycolate, generating urea and glyoxylate. Involved in the anaerobic utilization of allantoin as sole nitrogen source. Reinforces the induction of genes involved in the degradation of allantoin and glyoxylate by producing glyoxylate.

ybbW
Putative allantoin transporter; Transport of allantoin.
 
   
 0.686
allB
Allantoinase; Catalyzes the conversion of allantoin (5-ureidohydantoin) to allantoic acid by hydrolytic cleavage of the five-member hydantoin ring; Belongs to the metallo-dependent hydrolases superfamily. Allantoinase family.
 
  
 0.681
yedV
Putative sensory kinase in two-component regulatory system with YedW; Member of a two-component regulatory system HprR/HprS involved in response to hydrogen peroxide. Senses H(2)O(2), maybe via the redox state of the membrane. Activates HprR by phosphorylation. Can also phosphorylate CusR.
 
    0.609
xanP
Xanthine permease; Specific, proton motive force-dependent high-affinity transporter for xanthine; Belongs to the xanthine/uracil permease family. Nucleobase:cation symporter-2 (NCS2) (TC 2.A.40) subfamily.
 
  
 0.586
xanQ
Xanthine permease; Specific, proton motive force-dependent high-affinity transporter for xanthine; Belongs to the xanthine/uracil permease family. Nucleobase:cation symporter-2 (NCS2) (TC 2.A.40) subfamily.
