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.

Predicted Functional Partners:
Isop_1517
DEAD/DEAH box helicase domain protein; COGs: COG0513 Superfamily II DNA and RNA helicase; InterProIPR014021: IPR001650: IPR014014: IPR000629: IPR 014001: IPR011545; KEGG: psl:Psta_1620 DEAD/DEAH box helicase domain protein; PFAM: DEAD/DEAH box helicase domain protein; helicase domain protein; SMART: DEAD-like helicase; helicase domain protein; SPTR: DEAD/DEAH box helicase domain protein; PFAM: Helicase conserved C-terminal domain; DEAD/DEAH box helicase; Belongs to the DEAD box helicase family.
  
 
 0.921
nusA
NusA antitermination factor; Participates in both transcription termination and antitermination.
 
  
 0.879
infB
Translation initiation factor IF-2; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.
  
  
 0.854
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.
  
  
 0.843
rho
Transcription termination factor Rho; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template.
   
  
 0.841
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.
  
  
 0.840
Isop_1104
Ribonuclease, Rne/Rng family; COGs: COG1530 Ribonuclease G and E; InterPro IPR003029: IPR004659: IPR019307; KEGG: psl:Psta_2436 ribonuclease, Rne/Rng family; PFAM: RNA-binding protein AU-1/Ribonuclease E/G; RNA binding S1 domain protein; SPTR: Ribonuclease, Rne/Rng family; TIGRFAM: ribonuclease, Rne/Rng family; PFAM: Ribonuclease E/G family; S1 RNA binding domain; TIGRFAM: ribonuclease, Rne/Rng family.
  
 
 0.837
rpsD
SSU ribosomal protein S4P; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.
   
  
 0.835
rplB
LSU ribosomal protein L2P; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.
   
 
 0.828
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.815
