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. (488 aa)    
Predicted Functional Partners:
guaA
GMP synthetase; 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.
 
 
 0.997
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase; Bifunctional; bifunctional purine biosynthesis protein PURH. (SW:PUR9_SALTY); IMP cyclohydrolase.
  
 
 0.993
gpt
Guanine-hypoxanthine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.978
hpt
Hypoxanthine phosphoribosyltransferase; Acts preferentially on hypoxanthine; has very low activity towards guanine. Inactive towards xanthine (By similarity). Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.976
yfeJ
Putative GMP synthase; Contains glutamine amidotransferase domain; hypothetical 18.7 Kda protein in pdxK-cysM intergenic region. (SW:YFEJ_SALTY).
  
 
 0.965
purB
Similar to E. coli adenylosuccinate lyase (AAC74215.1); Blastp hit to AAC74215.1 (456 aa), 94% identity in aa 1 - 456.
  
  
 0.961
surE
Survival protein, protein damage control; Nucleotidase with a broad substrate specificity as it can dephosphorylate various ribo- and deoxyribonucleoside 5'-monophosphates and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP. Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the preference for short-chain-length substrates (P20-25). Might be involved in the regulation of dNTP and NTP pools, and in the turnover of 3'-mononucleotides produced by numerous intracellular RNases (T1, T2, and F) during the degradation of various RNAs.
    
 0.945
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
 
 
 0.941
gsk
Similar to E. coli inosine-guanosine kinase (AAC73579.1); Blastp hit to AAC73579.1 (434 aa), 94% identity in aa 1 - 434.
   
 
 0.940
