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

pheTphenylalanine--tRNA ligase subunit beta; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily. (804 aa)    
Predicted Functional Partners:
pheS
phenylalanine--tRNA ligase subunit alpha; Catalyzes a two-step reaction, first charging a phenylalanine molecule by linking its carboxyl group to the alpha-phosphate of ATP, followed by transfer of the aminoacyl-adenylate to its tRNA; forms a heterotetramer of alpha(2)beta(2); binds two magnesium ions per tetramer; type 1 subfamily; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily.
 
 0.999
leuS
leucine--tRNA ligase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-I aminoacyl-tRNA synthetase family.
  
  
 0.974
ileS
isoleucine--tRNA ligase; 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.
  
 
 0.960
guaA
GMP synthetase; Catalyzes the synthesis of GMP from XMP.
  
  
 0.927
metG
methionine--tRNA ligase; 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. MetG type 2B subfamily.
  
  
 0.922
rpsB
30S ribosomal protein S2; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the universal ribosomal protein uS2 family.
  
 
 0.917
rplO
50S ribosomal protein L15; Binds to the 23S rRNA; Belongs to the universal ribosomal protein uL15 family.
  
  
 0.897
rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
  
 0.894
tyrS
tyrosine--tRNA ligase; Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two- step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr); Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 1 subfamily.
  
  
 0.855
guaB
IMP 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.
