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.

guaBInosine-5'-monophosphate 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. (487 aa)    
Predicted Functional Partners:
guaA
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.
 0.999
purH
Bifunctional purine biosynthesis protein PurH.
  
 0.993
purA
Adenylosuccinate synthetase; 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.
 
 
 0.989
MVIS_0917
Glutamine amidotransferase.
  
 
 0.954
gpt
Xanthine phosphoribosyltransferase (xanthine-guanin phosphoribosyltransferase); Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.933
hpt
Hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.925
MVIS_2162
Putative phosphatase, SurE family.
    
 0.922
guaC
GMP reductase; 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.
  
  
 
0.921
rdgB
Nucleoside-triphosphatase rdgB; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
  
 0.920
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.
  
 
 0.915
