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.

sigOAlternative sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Together with its coactivator RsoA, positively regulates the expression of at least three operons, including oxdC-yvrL, sigO-rsoA and yvrJ. Required for the acid stress-dependent induction of the oxalate decarboxylase oxdC. (176 aa)    
Predicted Functional Partners:
rsoA
Regulator of sigma-O; Together with RNA polymerase sigma factor SigO, positively regulates the expression of at least three operons, including oxdC- yvrL, sigO-rsoA and yvrJ. Required for the acid stress-dependent induction of the oxalate decarboxylase oxdC.
  
 
 0.993
yvrL
Putative integral inner membrane protein; Negatively regulates RNA polymerase sigma factor SigO- dependent transcription. Prevents the expression or secretion of OxdC under nonstress conditions. May act as an anti-sigma factor.
  
  
 0.971
flgM
Anti-sigma factor repressor of sigma(D)-dependent transcription; Allows the coupling of early and late flagellar synthesis through the repression of RNA polymerase sigma-D factor-dependent transcription.
  
 
 0.865
rpoC
RNA polymerase (beta' subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.844
rpoB
RNA polymerase (beta subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.821
oxdC
Oxalate decarboxylase; Converts oxalate to formate and CO(2) in an O(2)-dependent reaction. Can also catalyze minor side reactions: oxalate oxidation to produce H(2)O(2), and oxalate-dependent, H(2)O(2)-independent dye oxidations.
  
  
 0.785
spoIIAB
Anti-sigma factor (antagonist of sigma(F)) and serine kinase; Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
  
 
 0.753
flgC
Flagellar component of cell-proximal portion of basal-body rod; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type s: structure; Belongs to the flagella basal body rod proteins family.
  
 
 0.735
rpoA
RNA polymerase (alpha subunit); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
    
 
 0.725
rpoZ
Omega subunit of RNA polymerase; 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).
   
 
 0.723
