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

Score
hprKHPr kinase (ptsK); 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) (By similarity). (319 aa)    
Predicted Functional Partners:
ptsH
Phosphocarrier protein HPr (ptsH); 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. The phosphoryl group from phosphoenolpyruvate (PEP) is transferred to the phosphoryl carrier protein HPr by enzyme I. Phospho-HPr then transfers it to the PTS EIIA domain.

pgl
Glucose-6-phosphate 1-dehydrogenase, putative; Hydrolysis of 6-phosphogluconolactone to 6-phosphogluconate.
  
  
 0.793
lgt
Prolipoprotein diacylglyceryl transferase (lgt); 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.
  
  
 0.792
TP_0939
Pyruvate oxidoreductase; Similar to PID:1001780 SP:P52965 PID:1006618 percent identity: 58.44; identified by sequence similarity; putative.
   
   0.613
TP_0307
Conserved hypothetical protein; Similar to GB:AE000783 percent identity: 21.80; identified by sequence similarity; putative.
   
 
 0.609
TP_0588
Conserved hypothetical protein; Similar to GB:AE000783 percent identity: 22.22; identified by sequence similarity; putative.
       0.608
nadE
NH(3)-dependent NAD(+) synthetase (nadE); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD.
   
  
 0.543
rpe
Ribulose-phosphate 3-epimerase (cfxE); Catalyzes the reversible epimerization of D-ribulose 5- phosphate to D-xylulose 5-phosphate; Belongs to the ribulose-phosphate 3-epimerase family.
     
 0.543
ptsN
PTS system, nitrogen regulatory IIA component (ptsN-2); Similar to GB:D12938 SP:P31222 GB:Z27094 PID:285783 PID:414887 percent identity: 29.86; identified by sequence similarity; putative.

TP_0261
Catabolite gene activator, putative; Similar to PID:1653345 percent identity: 30.99; identified by sequence similarity; putative.
