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

guaAGMP synthase; Catalyzes the synthesis of GMP from XMP. (501 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.
 0.999
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.999
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.998
TM_0159
Ham1 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.
 
 
 0.996
TM_0206
Hypoxanthine phosphoribosyltransferase; Similar to GB:D26185 SP:P37472 PID:467457 GB:AL009126 percent identity: 66.67; identified by sequence similarity; putative; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.995
argS
arginyl-tRNA synthetase; Similar to SP:P46906 PID:971336 PID:2224756 GB:AL009126 percent identity: 67.62; identified by sequence similarity; putative.
  
  
 0.995
surE
Stationary phase survival protein; Nucleotidase that preferentially dephosphorylates 5'-GMP and 5'-AMP.
    
 0.995
TM_1878
UDP-sugar hydrolase; Similar to SP:P07024 PID:757842 GB:U00096 PID:1773162 PID:1786687 percent identity: 62.97; identified by sequence similarity; putative; Belongs to the 5'-nucleotidase family.
    
 0.993
TM_0360
mazG-related protein; Similar to GB:L42023 SP:P44723 PID:1003804 PID:1222392 PID:1204710 percent identity: 60.62; identified by sequence similarity; putative.
    
  0.992
rplK
Ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
  
    0.991
