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

ptsHPhosphocarrier protein HPr (histidine-containing protein). (87 aa)    
Predicted Functional Partners:
manL
Mannose PTS system component IIAB.
  
 0.999
ptsI
Phosphoenolpyruvate:sugar phosphotransferase system enzyme I; 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).

scrA
Sucrose PTS component II.
  
 0.976
manN
Mannose PTS system component IID.
    
 0.972
stu0192
Glucose PTS enzyme component IIABC, truncated; Truncated.
 
 0.965
manM
Mannose PTS system component IIC.
    
 0.958
ptsK
Hpr 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). The two antagonistic activities of HprK/P are regulated by several intracellular metabolites, which change their concentration in response to the absence or presence of rapidly metabolisable carbon s [...]

celB
Similar to cellobiose PTS system component IIC.
    
 0.905
stu0401
Fructose PTS system component IIABC, truncated; Truncated.
