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

ptsOPhosphocarrier protein HPr-like NPr; Nitrogen related; exchanges phosphate with Enzyme I; similar to E. coli phosphocarrier protein HPr-like NPr, nitrogen related, exchanges phosphate with Enzyme I, Hpr (AAC76238.1); Blastp hit to AAC76238.1 (90 aa), 96% identity in aa 1 - 90. (90 aa)    
Predicted Functional Partners:
ptsP
General PTS system enzyme I, transcriptional regulator with NPR and NTR proteins; Component of the phosphoenolpyruvate-dependent nitrogen- metabolic phosphotransferase system (nitrogen-metabolic PTS), that seems to be involved in regulating nitrogen metabolism. Enzyme I-Ntr transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein (NPr). Could function in the transcriptional regulation of sigma-54 dependent operons in conjunction with the NPr (PtsO) and EIIA-Ntr (PtsN) proteins. Enzyme I-Ntr is specific for NPr.

ptsN
Sugar specific PTS family enzyme IIA; Also regulates N metabolism; similar to E. coli phosphotransferase system enzyme IIA, regulates N metabolism (AAC76236.1); Blastp hit to AAC76236.1 (163 aa), 95% identity in aa 1 - 163.

yhbJ
Putative P-loop-containing kinase; Modulates the synthesis of GlmS, by affecting the processing and stability of the regulatory small RNA GlmZ. When glucosamine-6- phosphate (GlcN6P) concentrations are high in the cell, RapZ binds GlmZ and targets it to cleavage by RNase E. Consequently, GlmZ is inactivated and unable to activate GlmS synthesis. Under low GlcN6P concentrations, RapZ is sequestered and inactivated by an other regulatory small RNA, GlmY, preventing GlmZ degradation and leading to synthesis of GlmS; Belongs to the RapZ-like family. RapZ subfamily.

fruA
Fructose-specific transport protein; Sugar Specific PTS system; similar to E. coli PTS system, fructose-specific transport protein (AAC75228.1); Blastp hit to AAC75228.1 (563 aa), 92% identity in aa 1 - 563.
  
  
 0.926
ptsA
General PTS family enzyme I; Similar to E. coli PEP-protein phosphotransferase system enzyme I (AAC76929.1); Blastp hit to AAC76929.1 (711 aa), 90% identity in aa 1 - 711.
 
 
 0.914
ptsI
PEP-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).
 
 
 0.909
yhbH
Putative sigma N modulation factor; During stationary phase, promotes and stabilizes dimerization of 70S ribosomes by the ribosome modulation factor (RMF), leading to the formation of inactive 100S ribosomes.
     
 0.855
fruF
Phosphoenolpyruvate-dependent sugar phosphotransferase system, EIIA 2; The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II FruAB PTS system is involved in fructose transport.
 
 
 
 0.835
rpoN
Sigma 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).

yhbG
Putative ABC superfamily transport protein; Atp_bind; similar to E. coli putative ATP-binding component of a transport system (AAC76233.1); Blastp hit to AAC76233.1 (241 aa), 98% identity in aa 1 - 241.
