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

SIQ22270.1PTS IIA-like nitrogen-regulatory protein PtsN. (156 aa)    
Predicted Functional Partners:
hprK
Hpr(Ser) kinase/phosphatase; Catalyzes the ATP- as well as the pyrophosphate-dependent phosphorylation of a specific serine residue in HPr, a phosphocarrier protein of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS). HprK/P also catalyzes the pyrophosphate-producing, inorganic phosphate-dependent dephosphorylation (phosphorolysis) of seryl-phosphorylated HPr (P-Ser-HPr).
 
  
 0.952
SIS06560.1
Phosphocarrier protein.
 
  
 0.873
PtsP
Phosphoenolpyruvate--protein phosphotransferase; General (non sugar-specific) component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). This major carbohydrate active-transport system catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. Enzyme I transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (HPr).
 
  
 0.862
RapZ
UPF0042 nucleotide-binding protein; Displays ATPase and GTPase activities.
  
  
 0.825
RaiA
SSU ribosomal protein S30P.
  
  
 0.815
SIS06550.1
PTS system, ascorbate-specific IIA component.
 
  
 0.726
RpoN
RNA polymerase, sigma 54 subunit, RpoN/SigL; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
 
  
 0.598
SIQ98407.1
Transcriptional regulator, DeoR family.
 
  
 0.564
SIQ19628.1
Ribulose-phosphate 3-epimerase; Belongs to the ribulose-phosphate 3-epimerase family.
  
  
 0.488
SIQ32423.1
D-arabinitol 4-dehydrogenase.
  
  
 0.487
