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

Tery_4426RNA polymerase, sigma 28 subunit; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (384 aa)    
Predicted Functional Partners:
rpoA
DNA-directed RNA polymerase, alpha subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.855
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication.
  
 0.841
rpoB
DNA-directed RNA polymerase, beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.823
Tery_4447
Multi-sensor hybrid histidine kinase; KEGG: ana:all2875 two-component hybrid sensor and regulator; TIGRFAM: PAS sensor protein; PFAM: CBS domain containing protein response regulator receiveR GAF ATP-binding region, ATPase-like histidine kinase A-like PAS fold-3 PAS fold; SMART: PAS PAC motif.
   
 
 0.807
rpoZ
DNA-directed RNA polymerase, omega subunit; 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.
    
 
 0.752
secA
Protein translocase subunit secA; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
 
 
 0.672
rpoC2
DNA-directed RNA polymerase, beta'' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Belongs to the RNA polymerase beta' chain family. RpoC2 subfamily.
  
 
 0.633
rpoC1
DNA-directed RNA polymerase, gamma subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.633
Tery_4425
PFAM: GCN5-related N-acetyltransferase; KEGG: ana:alr4250 probable N-acetyltransferase.
  
    0.543
nusA
NusA antitermination factor; Participates in both transcription termination and antitermination.
  
 
 0.536
