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

allRGlyoxylate-inducible transcriptional repressor of all and gcl operons; Negative regulator of allantoin and glyoxylate utilization operons. Binds to the gcl promoter and to the allS-allA intergenic region. Binding to DNA is abolished by glyoxylate. (271 aa)    
Predicted Functional Partners:
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.
     
 0.900
allS
allD operon transcriptional activator; Positive regulator essential for the expression of allD operon. Binds to the allD promoter; Belongs to the LysR transcriptional regulatory family.
     
 0.872
gcl
Glyoxylate carboligase; Catalyzes the condensation of two molecules of glyoxylate to give 2-hydroxy-3-oxopropanoate (also termed tartronate semialdehyde).
     
 0.832
mhpR
Mhp operon transcriptional activator; Activator of the mhpABCDFE operon coding for components of the 3-hydroxyphenylpropionate degradation pathway.
  
   
 0.682
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.
     
 0.628
rutR
Rut operon transcriptional repressor for; Master transcription regulator which represses the degradation of pyrimidines (rutABCDEFG) and purines (gcl operon) for maintenance of metabolic balance between pyrimidines and purines. It also regulates the synthesis of pyrimidine nucleotides and arginine from glutamine (carAB) and the supply of glutamate (gadABWX).
      
 0.620
allD
Ureidoglycolate dehydrogenase; AllD plays a pivotal role as a metabolic branch-point enzyme in nitrogen utilization via the assimilation of allantoin. It is able to utilize allantoin as a sole source of nitrogen under anaerobic conditions. Catalyzes the oxidation of ureidoglycolate to oxalurate.
     
 0.523
hyi
Hydroxypyruvate isomerase; Catalyzes the reversible isomerization between hydroxypyruvate and 2-hydroxy-3-oxopropanoate (also termed tartronate semialdehyde). Does not catalyze the isomerization of D-fructose to D- glucose or that of D-xylulose to D-xylose. Also does not catalyze racemization of serine, alanine, glycerate or lactate.
       0.522
ascG
Asc operon transcriptional repressor; Repressor of the asc operon. The cryptic operon is activated by the insertion of IS186 into the ascG gene.
      
 0.503
caiC
Putative crotonobetaine/carnitine-CoA ligase; Catalyzes the transfer of CoA to carnitine, generating the initial carnitinyl-CoA needed for the CaiB reaction cycle. Also has activity toward crotonobetaine and gamma-butyrobetaine. Belongs to the ATP-dependent AMP-binding enzyme family.
