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

rpoNSigma N factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of enzymes involved in arginine catabolism. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for the receipt of the melting signal from the remotely bound activator protein GlnG(NtrC). (477 aa)    
Predicted Functional Partners:
glnG
EBP family response regulator in two-component regulatory system with GlnL; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.

rpoE
Sigma E (sigma 24) factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase (RNAP) to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma-E controls the envelope stress response, responding to periplasmic protein stress, increased levels of periplasmic lipopolysaccharide (LPS) as well as acid stress, heat shock and oxidative stress; it controls protein processing in the extracytoplasmic compartment (By similarity).

yfhA
EBP family; similar to E. coli putative 2-component transcriptional regulator (AAC75607.1); Blastp hit to AAC75607.1 (444 aa), 95% identity in aa 1 - 444.
 
 
 0.958
pspF
Similar to E. coli psp operon transcriptional activator (AAC74385.1); Blastp hit to AAC74385.1 (330 aa), 86% identity in aa 6 - 330.
 
 
 
 0.955
rpoH
Sigma H factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is involved in regulation of expression of heat shock genes.
   
  
 0.949
rpoD
Sigma D factor of RNA polymerase; 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.

STM0571
Putative inner membrane protein; Unknown (gi|2896134).
 
 
 
 0.933
STM4534
Putative NtrC family transcriptional regulator, ATPase domain protein; Similar to E. coli psp operon transcriptional activator (AAC74385.1); Blastp hit to AAC74385.1 (330 aa), 38% identity in aa 13 - 242.
 
 
 
 0.930
rpoS
Sigma S (sigma 38) factor of RNA polymerase; 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 master transcriptional regulator of the stationary phase and the general stress response.
   
  
 0.927
fliA
Sigma F (sigma 28) factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor controls the expression of flagella-related genes. May regulate the expression of genes involved in virulence.
