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

ptsOPhosphohistidinoprotein-hexose phosphotransferase; Component of the phosphoenolpyruvate-dependent nitrogen- metabolic phosphotransferase system (nitrogen-metabolic PTS), that seems to be involved in regulating nitrogen metabolism. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein NPr by enzyme I-Ntr. Phospho-NPr then transfers it to EIIA-Ntr. Could function in the transcriptional regulation of sigma-54 dependent operons in conjunction with the NPr (PtsO) and EIIA-Ntr (PtsN) proteins; Belongs to the HPr family. (90 aa)    
Predicted Functional Partners:
ptsI_1
Phosphoenolpyruvate-protein phosphotransferase; Member of a second PTS chain involved in nitrogen metabolism; PtsP phosphorylates NPr; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the PEP-utilizing enzyme family.
  
 
 0.991
ptsN
PTS system nitrogen regulatory protein IIA(Ntr); Seems to have a role in regulating nitrogen assimilation.
 
 
 0.989
ptsI_2
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).

AKL37011.1
PTS fructose transporter subunit IIA; Phosphotransferase system, enzyme I; transfers the phosphoryl group from phosphoenolpyruvate (PEP) to the phosphoryl carrier protein HPr; HPr transfers the phosphoryl group to subunit A; subunit IIA transfers a phosphoryl group to subunit IIB; subunit IIB transfers the phosphoryl group to the substrate; part of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active-transport system; Derived by automated computational analysis using gene prediction method: Protein Homology.

rapZ
glmZ(sRNA)-inactivating NTPase; 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.

AKL34320.1
DhaM; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the PEP-utilizing enzyme family.
 
 
 0.869
fruA_4
PTS system fructose-specific transporter subunits IIBC; Phosphoenolpyruvate-dependent sugar phosphotransferase system; catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane; IIB is phosphorylated by IIA and then transfers the phosphoryl group to the sugar; IIC forms the translocation channel; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.810
mtlA_1
PTS system mannitol-specific transporter subunit IICBA; Catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane; subunit IIC forms the translocation channel and contains the specific substrate-binding site; subunit IIA is phosphorylated and transfers the phosphoryl group to the IIB subunit; subunit IIB transfers the phosphoryl group to the substrate; Derived by automated computational analysis using gene prediction method: Protein Homology.

rpoN
RNA polymerase factor sigma-54; 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 nitrogen fixation genes. 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 NifA for the expression of the nitrogen fixation proteins.
 
  
 0.726
hpf
Ribosome hibernation promoting factor HPF; During stationary phase, promotes and stabilizes dimerization of 70S ribosomes by the ribosome modulation factor (RMF), leading to the formation of inactive 100S ribosomes. Belongs to the HPF/YfiA ribosome-associated protein family. Short HPF subfamily.
