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

pheTPhenylalanyl-tRNA synthetase, beta subunit; Function of strongly homologous gene; enzyme. (572 aa)    
Predicted Functional Partners:
pheS
Phenylalanyl-tRNA synthetase, alpha subunit; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 2 subfamily.
 
 0.999
rpsC
30S ribosomal protein S3; Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation; Belongs to the universal ribosomal protein uS3 family.
  
 
 0.932
rsmB
Ribosomal RNA small subunit methyltransferase B; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
 
  
 0.920
ileS
Isoleucyl-tRNA synthetase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 1 subfamily.
 
 
 0.882
leuS
Leucyl-tRNA synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.865
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.852
metG
Methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.837
rpsB
30S ribosomal protein S2; Function of homologous gene experimentally demonstrated in an other organism; structure; Belongs to the universal ribosomal protein uS2 family.
   
 
 0.806
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.
   
  
 0.788
argS
Arginyl-tRNA synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
  
 0.782
