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

ychFGTP-binding protein YchF; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner. (369 aa)    
Predicted Functional Partners:
pth
Peptidyl-tRNA hydrolase; The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Belongs to the PTH family.
 
  
 0.856
prfA
Peptide chain release factor 1; Peptide chain release factor 1 directs the termination of translation in response to the peptide chain termination codons UAG and UAA.
 
  
 0.760
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.
  
  
 0.758
argS
Arginyl-tRNA synthetase; PFAM: DALR anticodon binding domain; Arginyl tRNA synthetase N terminal domain; tRNA synthetases class I (R); TIGRFAM: arginyl-tRNA synthetase; COGs: COG0018 Arginyl-tRNA synthetase; HAMAP: Arginyl-tRNA synthetase, class Ic; InterPro IPR005148:IPR015945:IPR008909:IPR001278; KEGG: sta:STHERM_c10230 hypothetical protein; PFAM: Arginyl-tRNA synthetase, class Ic, core; Arginyl tRNA synthetase, class Ic, N-terminal; DALR anticodon binding; SPTR: Arginyl-tRNA synthetase; TIGRFAM: Arginyl-tRNA synthetase, class Ic.
 
  
 0.737
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.731
AEJ61099.1
PFAM: Phosphoribosyl transferase domain; TIGRFAM: ribose-phosphate pyrophosphokinase; COGs: COG0462 Phosphoribosylpyrophosphate synthetase; InterPro IPR005946:IPR000836; KEGG: sta:STHERM_c13320 hypothetical protein; PFAM: Phosphoribosyltransferase; SPTR: Ribose-phosphate pyrophosphokinase; TIGRFAM: Phosphoribosyl pyrophosphokinase.

topA
DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]
  
  
 0.660
rpsG
Ribosomal protein S7; 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.
  
 
 0.654
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.
 
  
 0.638
gltX
glutamyl-tRNA synthetase; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu); Belongs to the class-I aminoacyl-tRNA synthetase family. Glutamate--tRNA ligase type 1 subfamily.
