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

CPS_4908Glutamine amidotransferase, class I; Identified by match to protein family HMM PF00117. (240 aa)    
Predicted Functional Partners:
guaB
Inosine-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.
  
 
 0.974
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.935
hpt
Hypoxanthine phosphoribosyltransferase; Identified by similarity to SP:P36766; match to protein family HMM PF00156; match to protein family HMM TIGR01203; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.921
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.919
surE
Acid phosphatase SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.918
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
    
 0.915
rdgB
rdgB protein; 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.
  
 
 0.910
CPS_0423
HAD-superfamily hydrolase, subfamily IA, variant 3 family protein; Identified by match to protein family HMM PF00702; match to protein family HMM TIGR01509.
    
  0.902
CPS_4114
Identified by match to protein family HMM PF03819; match to protein family HMM TIGR00444.
     
  0.900
CPS_4907
Putative membrane protein.
 
     0.649
