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

sigARNA 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. (502 aa)    
Predicted Functional Partners:
rpoB
DNA-directed RNA polymerase beta chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.993
rpoC
DNA-directed RNA polymerase beta' chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
 
 
 0.991
rpoA
DNA-directed RNA polymerase alpha chain; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
  
 
 0.990
rbpA
Conserved hypothetical protein; Binds to RNA polymerase (RNAP), stimulating transcription from principal, but not alternative sigma factor promoters. Belongs to the RNA polymerase-binding protein RbpA family.
    
 
 0.990
rpoZ
Putative DNA-directed RNA polymerase omega chain; 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.
   
 
 0.986
DIP1974
Putative CarD-like transcriptional factor; N-terminal region is similar to Mycobacterium tuberculosis putative transcriptional factor Rv3583c TR:O53568 (EMBL:AL022075) (162 aa) fasta scores: E(): 6.8e-38, 71.69% id in 159 aa, and to Mycobacterium leprae putative transcription factor ML0320 TR:Q9CCW7 (EMBL:AL583918) (165 aa) fasta scores: E(): 1.2e-37, 70.44% id in 159 aa.
   
 
 0.896
whiB-3
Putative transcriptional regulator; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
    
 
 0.785
dnaG
DNA primase; RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Belongs to the DnaG primase family.
 
  
 0.760
DIP1710
Similar to Mycobacterium tuberculosis CDC1551 ferric uptake regulation protein MT2428 TR:AAK46722 (EMBL:AE007082) (130 aa) fasta scores: E(): 6.1e-24, 53.6% id in 125 aa, and to Escherichia coli ferric uptake regulation protein Fur or B0683 or Z0831 or ECS0714 SW:FUR_ECOLI (P06975) (148 aa) fasta scores: E(): 2.4e-10, 29.77% id in 131 aa; Belongs to the Fur family.
  
 
 0.684
nusA
Putative N utilization related protein; Participates in both transcription termination and antitermination.
 
 
 0.617
