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

guaBIMP dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family. (501 aa)    
Predicted Functional Partners:
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
 0.999
purA
Adenylosuccinate synthase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
  
 
 0.979
murI
Glutamate racemase; Provides the (R)-glutamate required for cell wall biosynthesis; Belongs to the aspartate/glutamate racemases family.
  
 0.974
KRM72003.1
GMP synthase glutamine amidotransferase subunit.
  
 
 0.961
xpt
Xanthine phosphoribosyltransferase; Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis.
  
 
 0.952
KRM71234.1
Hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.952
guaC
Guanosine 5-monophosphate oxidoreductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides; Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
  
  
0.928
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.893
KRM71279.1
Pur operon repressor.
  
 
 0.890
KRM71244.1
CBS domain-containing protein.
  
 
 0.883
