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

PP_2259Putative sigma-54 dependent transcriptional regulator; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator. (591 aa)    
Predicted Functional Partners:
PP_2260
Putative glycerol-phosphate ABC transporter, ATP-binding protein; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative transporter; Belongs to the ABC transporter superfamily.
 
  
 0.870
PP_2263
Sugar ABC transporter, permease protein.
  
  
 0.837
rpoN
RNA polymerase sigma-54 factor; 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 the xylCAB operon and the xylS gene. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator protein XylR for the expression of the xylCAB operon and xylS.
