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

ychFHypothetical protein; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner. (371 aa)    
Predicted Functional Partners:
pth
peptidyl-tRNA hydrolase, PTH1 family; The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Belongs to the PTH family.
 
  
 0.888
lepA
GTP-binding protein LepA; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.
 
  
 0.779
pyrG
CTP synthase; 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.
   
 
 0.730
pheT
phenylalanyl-tRNA synthetase beta subunit; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.726
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. MetG type 2B subfamily.
  
  
 0.714
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.690
SDB01595.1
Hypothetical protein.
  
  
 0.681
prfA
Bacterial peptide chain release factor 1 (bRF-1); Peptide chain release factor 1 directs the termination of translation in response to the peptide chain termination codons UAG and UAA.
 
  
 0.678
argS
arginyl-tRNA synthetase.
 
  
 0.675
SDB04315.1
Ribonucleoside-diphosphate reductase class Ib alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
     
 0.668
