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.

HI_1459Sigma factor, putative; Similar to GB:AL009126 percent identity: 26.75; identified by sequence similarity; putative; Belongs to the sigma-70 factor family. ECF subfamily. (194 aa)    
Predicted Functional Partners:
rseA
sigma-E factor negative regulatory protein (mclA); An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytopl [...]

rpoB
DNA-directed RNA polymerase, beta chain (rpoB); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.752
rpoC
DNA-directed RNA polymerase, beta' chain (rpoC); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.747
rpoA
DNA-directed RNA polymerase, alpha chain (rpoA); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.721
rpoZ
DNA-directed RNA polymerase, omega chain (rpoZ); 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 (By similarity).

HI_0589
Sigma factor regulatory protein, putative; Similar to SP:P46187 PID:987645 PID:1045631 PID:1050877 GB:U00096 percent identity: 29.01; identified by sequence similarity; putative.
  
  
 0.505
topA
DNA topoisomerase I (topA); Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing D [...]

polA
DNA polymerase I (polA); In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity.
 
   
 0.488
HI_1052
Transcriptional regulator, araC family, putative; Similar to SP:P35319 PID:581707 percent identity: 25.67; identified by sequence similarity; putative.
  
    0.446
rseB
sigma-E factor regulatory protein (rseB); Negatively modulates the activity of sigma-E (RpoE) by stabilizing RseA under non-stress conditions. Although not essential for association of sigma-E with Rsea it increases their affinity 2- to 3-fold. When bound to RseA it prevents proteolysis by DegS, which is probably relieved by lipopolysaccharide binding (LPS) (By similarity). Belongs to the RseB family.
