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.

sigBRNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. (329 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.
 
 
 0.944
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.
 
 
 0.928
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.
  
 
 0.918
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.
    
 
 0.901
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.
   
 
 0.887
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.
   
 
 0.878
rpoE
Similar to Mycobacterium tuberculosis RNA polymerase sigma-E factor RpoE or SigH or Rv3223c or MT3320 or MTCY07D11.03 SW:RPOE_MYCTU (O05843) (216 aa) fasta scores: E(): 1e-44, 70.33% id in 182 aa; Belongs to the sigma-70 factor family. ECF subfamily.
   
  
 0.865
galE
UDP-glucose 4-epimerase; Involved in the metabolism of galactose. Catalyzes the conversion of UDP-galactose (UDP-Gal) to UDP-glucose (UDP-Glc) through a mechanism involving the transient reduction of NAD (By similarity).
     
 0.845
dtxR
Diphtheria toxin repressor; Iron-binding repressor of the dipheteria toxin gene expression. May serve as a global regulator of gene expression. Represses ripA under iron excess.
  
  
 0.799
whiB-3
Putative transcriptional regulator; Acts as a transcriptional regulator. Probably redox- responsive. The apo- but not holo-form probably binds DNA.
    
 
 0.734
