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

hprKProbable Hpr serine 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). (313 aa)    
Predicted Functional Partners:
ptsN
protein-Npi-phosphohistidine-sugar phosphotransferase; Probable nitrogen regulatory IIA protein,; High confidence in function and specificity.
 
  
 0.941
ptsH
Phosphocarrier protein HPr (Histidine-containing protein) (Protein H). This is a component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active -transport system. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the permease (enzymes II/III). HPr is common to all PTS (By similarity). 64% HPr_HisP_S.IPR000032; HPr_protein.IPR002114; HPr_SerP_S. IPR005698; PTS_HPr. Pfam:PF00381; PTS-HPr; 1; High confidence in function and specificity.
 
 
 
 0.873
ptsI
Putative 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).
 
   
 0.817
rpoX
Probable sigma 54 modulation protein,; High confidence in function and specificity.
     
 0.637
yhbG
Probable ABC transporter ATP-binding protein HI1148. ATP-binding cassette (ABC) transporters are multidomain membrane proteins, responsible for the controlled efflux and influx of substances (allocrites) across cellular membranes. TREMBL:Q7NST9: 64% identity,75% similarity InterPro: IPR003593; AAA_ATPase. IPR003439; ABC_transporter. IPR000767; Disease_resist. IPR003016; Lipoyl_BS. Pfam PF00005; ABC_tran; 1 mobB: molybdopterin-guanine dinucleoti TMH's present 0; High confidence in function and specificity.
     
 0.604
rpoN1
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.
     
 0.573
ptsL
This is a component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active -transport system. The IICD domains contain the sugar binding site and the transmembrane channel; the IIA domain contains the primary phosphorylation site (the donor is phospho-HPr); IIA transfers its phosphoryl group to the IIB domain which finally transfers it to the sugar. 32% EIIA-man.IPR004720; PTSIIB_sorb. Pfam:PF03610; EIIA-man; 1.PF03830; PTSIIB_sorb; 1; Specificity unclear.
 
   
 0.568
lgt
Probable prolipoprotein diacylglyceryl transferase; Catalyzes the transfer of the diacylglyceryl group from phosphatidylglycerol to the sulfhydryl group of the N-terminal cysteine of a prolipoprotein, the first step in the formation of mature lipoproteins; Belongs to the Lgt family.
  
  
 0.558
ilvA
Probable threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA.
     
 0.547
recX
Probable RecX-family regulatory protein; Modulates RecA activity; Belongs to the RecX family.
