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

purAAdenylosuccinate 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. (431 aa)    
Predicted Functional Partners:
purB
Adenylosuccinate lyase; Identified by match to protein family HMM PF00206; match to protein family HMM TIGR00928; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
 
 0.995
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.
 
 
 0.980
purH
Bifunctional purine biosynthesis protein PurH; Identified by match to protein family HMM PF01808; match to protein family HMM PF02142; match to protein family HMM TIGR00355.
  
 0.975
tilS
Putative bifunctional protein tilS/hprT; Ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. Belongs to the tRNA(Ile)-lysidine synthase family.
  
 
 0.952
pyrB
Aspartate carbamoyltransferase; Identified by match to protein family HMM PF00185; match to protein family HMM PF02729; match to protein family HMM TIGR00670; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
  
 
 0.932
trd_1303
Aspartate aminotransferase A; Identified by match to protein family HMM PF00155; match to protein family HMM PF00266.
  
 0.921
murI
Aspartate racemase; Identified by match to protein family HMM PF01177; match to protein family HMM TIGR00035; Belongs to the aspartate/glutamate racemases family.
     
  0.900
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 
  
 0.855
glyA
Serine hydroxymethyltransferase; 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.
  
  
 0.764
purD
Phosphoribosylamine--glycine ligase; Identified by match to protein family HMM PF01071; match to protein family HMM PF02843; match to protein family HMM PF02844; match to protein family HMM TIGR00877; Belongs to the GARS family.
