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

ychFConserved hypothetical GTP-binding protein; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner (By similarity). Does not hydrolyze GTP; Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family. YchF/OLA1 subfamily. (363 aa)    
Predicted Functional Partners:
pth
peptidyl-tRNA hydrolase (pth); The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Belongs to the PTH family.
 
  
 0.965
lepA
GTP-binding membrane 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.
 
  
 0.785
pheT
phenylalanyl-tRNA synthetase, beta subunit (pheT); Similar to GB:K02844 SP:P07395 PID:146346 PID:43071 GB:U00096 percent identity: 65.28; identified by sequence similarity; putative; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.725
fusA
Elongation factor G (fusA); Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome (By similarity); Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. [...]
 
 
 0.706
prfA
Peptide chain release factor 1 (prfA); Peptide chain release factor 1 directs the termination of translation in response to the peptide chain termination codons UAG and UAA.
 
  
 0.706
metG
methionyl-tRNA synthetase (metG); Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
  
  
 0.688
argS
arginyl-tRNA synthetase (argS); Similar to SP:P11875 GB:X15320 PID:581040 GB:U00096 PID:1736522 percent identity: 71.40; identified by sequence similarity; putative.
  
  
 0.680
pyrG
CTP synthetase (pyrG); 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.
   
 
 0.655
guaA
GMP synthase (guaA); Catalyzes the synthesis of GMP from XMP.
  
  
 0.647
rpsG
Ribosomal protein S7 (rpS7); One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the head domain of the 30S subunit. Is located at the subunit interface close to the decoding center, probably blocks exit of the E-site tRNA; Belongs to the universal ribosomal protein uS7 family.
