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

guaABGMP synthase (guaA-1); Catalyzes the synthesis of GMP from XMP. (303 aa)    
Predicted Functional Partners:
guaAA
GMP synthase (guaA-2); Catalyzes the synthesis of GMP from XMP.
  
 0.998
pyrG
CTP synthase (pyrG); Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
 
 0.991
purB
Adenylosuccinate lyase (purB); Similar to GB:L77117 PID:1591600 percent identity: 52.27; identified by sequence similarity; putative.
 
  
 0.965
surE
surE stationary-phase survival protein (surE); Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.962
AF_2237
HAM1 protein; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides xanthosine triphosphate (XTP), deoxyinosine triphosphate (dITP) and ITP. Probably functions 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. Shows very low activity on dGTP or dUTP, and has nearly no activity toward the canonical nucleotides ATP, CTP, and TTP; Belongs to [...]
 
 
 0.955
purL
Phosphoribosylformylglycinamidine synthase II (purL); Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to [...]

AF_1811
Inosine monophosphate cyclohydrolase; Similar to SP:P15639 GB:J05126 GB:X51950 PID:147420 PID:396345 percent identity: 38.27; identified by sequence similarity; putative.
 
  
 0.917
AF_0256
Conserved hypothetical protein; Similar to GB:L77117 SP:Q57600 PID:1498904 percent identity: 39.08; identified by sequence similarity; putative.
     
 0.915
argS
arginyl-tRNA synthetase (argS); Similar to GB:L77117 SP:Q57689 PID:1590971 percent identity: 48.77; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.906
purA
Adenylosuccinate synthetase (purA); 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.
