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.

sigHRNA polymerase sigma-70 factor, family protein; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released. This sigma factor is involved in heat shock and oxidative stress responses. (219 aa)    
Predicted Functional Partners:
rshA
Anti-sigma factor, family protein; A redox-regulated anti-sigma factor for cognate extracytoplasmic function (ECF) sigma factor SigH. ECF sigma factors are held in an inactive form by an anti-sigma factor (Probable). Overexpression leads to increased susceptibility to diamide.
  
 
 0.980
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. This subunit often mutates to generate rifampicin (Rif) resistance. Interaction with RbpA partially restores Rif-inhibited transcription; once the subunit is Rif-resistant however RbpA no longer stimulates transcription.
   
 
 0.779
rpoC
DNA-directed RNA polymerase, beta' subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 
 0.741
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.
  
 
 
 0.731
pknB
Serine-threonine protein kinase; Protein kinase that regulates many aspects of mycobacterial physiology. Is a key component of a signal transduction pathway that regulates cell growth, cell shape and cell division via phosphorylation of target proteins (By similarity). Probably phosphorylates RseA.
   
 
 0.703
whiB3
Transcription factor WhiB; A redox-sensitive transcriptional regulator. Maintains intracellular redox homeostasis by regulating catabolic metabolism and polyketide biosynthesis. Regulates expression of the redox buffer ergothioneine (ERG). In concert with myothiol (MSH), another redox buffer, responds to low pH leading to acid resistance. The apo- but not holo-form probably binds DNA (By similarity).
 
  
 0.658
rseA
Conserved hypothetical protein; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor SigE. ECF sigma factors are held in an inactive form by an anti-sigma factor (By similarity); Belongs to the zinc-associated anti-sigma factor (ZAS) superfamily.
  
 
 0.649
clgR
Transcriptional regulator, XRE family protein; Probably controls the response to vancomycin treatment; vancomycin induces expression of the clp regulon (clpP1, clpP2 and clpC1).
 
  
 0.628
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.
    
 
 0.603
ecf
Extra cytoplasmic sigma factor; Identified by match to protein family HMM PF04542; match to protein family HMM TIGR02937; Belongs to the sigma-70 factor family.
      
 0.563
