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

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. (482 aa)    
Predicted Functional Partners:
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
 0.999
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.
 
 
 0.993
purH
Bifunctional phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; COG0138 AICAR transformylase/IMP cyclohydrolase PurH (only IMP cyclohydrolase domain in Aful).
  
 
 0.988
ISM_06100
Glutamate synthase, large subunit; COG0067 Glutamate synthase domain 1.
  
 
 0.979
gpt
Xanthine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.950
ISM_07330
COG0518 GMP synthase - Glutamine amidotransferase domain.
  
 
 0.947
ISM_06700
Putative deoxyribonucleotide triphosphate pyrophosphatase; 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.
 
 0.946
surE
Survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.946
ISM_15320
COG0518 GMP synthase - Glutamine amidotransferase domain.
  
 
 0.939
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine.
 
 
 0.925
