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

purA-2Adenylosuccinate 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. (445 aa)    
Predicted Functional Partners:
purB
Adenylosuccinate lyase protein (purB); Psort: bacterial inner membrane --- Certainty= 0.185(Affirmative); COG0015 PurB adenylosuccinate lyase; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
 
 0.987
guaB
Inosine monophosphate dehydrogenase (guaB); 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.
  
 
 0.978
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase (AICAR transformylase)(purH); Psort: bacterial inner membrane --- Certainty= 0.162(Affirmative); COG0138 PurH AICAR transformylase/IMP cyclohydrolase PurH.
  
 0.965
pyrB
Aspartate carbamoyltransferase pyrB (pyrB); Psort: bacterial inner membrane --- Certainty= 0.119(Affirmative); COG0540 PyrB aspartate carbamoyltransferase, catalytic chain; Belongs to the aspartate/ornithine carbamoyltransferase superfamily.
  
 
 0.914
aatA
Aspartate aminotransferase A (aatA); Psort: bacterial cytoplasm --- Certainty= 0.178(Affirmative); COG0075 - serine-pyruvate aminotransferase/archaeal aspartate aminotransferase.
   
 0.910
surE
Stationary-phase survival protein (surE); Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.903
lysC
Aspartokinase (lysC); Psort: bacterial inner membrane --- Certainty= 0.183(Affirmative); COG0527 LysC aspartokinases; Belongs to the aspartokinase family.
  
 
  0.821
guaA
GMP synthase (glutamine-hydrolyzing) (guaA); Catalyzes the synthesis of GMP from XMP.
  
  
 0.806
glyA
Glycine/serine hydroxymethyltransferase (glyA); Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
  
  
 0.711
rplK
50S ribosomal protein L11 (rplK); Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
  
    0.703
