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.

rpoDRNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth. (662 aa)    
Predicted Functional Partners:
rpoB
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 0.990
rpoA
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 0.989
rpoC
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 0.985
rpoZ
DNA-directed RNA polymerase; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
 
 
 0.985
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
 
  
 0.942
nusA
Putative N utilization substance protein A; Participates in both transcription termination and antitermination.
 
 
 0.887
sspA2
Probable Stringent starvation protein A. Homology to sspA of E. coli of 43% (sprot|SSPA_ECOLI). FORMS AN EQUIMOLAR COMPLEX WITH THE RNA POLYMERASE HOLOENZYME (RNAP) BUT NOT WITH THE CORE ENZYME. IT IS SYNTHESIZED PREDOMINANTLY WHEN CELLS ARE EXPOSED TO AMINO ACID STARVATION AT WHICH TIME IT ACCOUNTS FOR OVER 50% OF THE TOTAL PROTEIN SYNTHESIZED. Pfam: Glutatione S-transferase,N-terminale domaine no TMHs; Family membership; Belongs to the GST superfamily.
  
 
 
 0.885
lepA
Probable GTP-binding protein; 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.
 
 
 0.882
vfr
Probable cyclic amp receptor-like protein,; High confidence in function and specificity.
    
 
 0.871
rpoH
RNA polymerase sigma-32 factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes.
