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

uhpAResponse regulator in two-component regulatory system wtih UhpB; Part of the UhpABC signaling cascade that controls the expression of the hexose phosphate transporter UhpT. Activates the transcription of the uhpT gene. Acts by binding specifically to the uhpT promoter region. (196 aa)    
Predicted Functional Partners:
uhpB
Sensory histidine kinase in two-component regulatory sytem with UhpA; Part of the UhpABC signaling cascade that controls the expression of the hexose phosphate transporter UhpT. UhpB functions as a membrane-associated protein kinase that autophosphorylates in response to interaction with UhpC, and subsequently transfers its phosphate group to the response regulator UhpA. Can also dephosphorylate UhpA.
 0.999
uhpC
Membrane protein regulates uhpT expression; Part of the UhpABC signaling cascade that controls the expression of the hexose phosphate transporter UhpT. UhpC senses external glucose-6-phosphate and interacts with the histidine kinase UhpB, leading to the stimulation of the autokinase activity of UhpB. Belongs to the major facilitator superfamily. Organophosphate:Pi antiporter (OPA) (TC 2.A.1.4) family.
  
 0.988
uhpT
Hexose phosphate transporter; Mediates the exchange of external hexose 6-phosphate and internal inorganic phosphate. Can transport glucose-6-phosphate, fructose-6-phosphate and mannose-6-phosphate. Also catalyzes the neutral exchange of internal and external phosphate.
   
 0.961
yhjB
Putative DNA-binding transcriptional response regulator; Putative regulator; Protein involved in transcription activator activity and transcription.
  
   
 0.866
csgD
csgBAC operon transcriptional regulator; The master regulator for adhesive curli fimbriae expression; necessary for transcription of the csgBAC/ymdA operon. Plays a positive role in biofilm formation. May have the capability to respond to starvation and/or high cell density by activating csgBA transcription. Low-level constitutive expression confers an adherent curli fimbriae- expressing phenotype, up-regulates 10 genes and down-regulates 14 others.
  
   
 0.864
ilvN
Acetolactate synthase I, valine sensitive, small subunit.
 
  
 0.829
glpT
Sn-glycerol-3-phosphate transporter; Responsible for glycerol-3-phosphate uptake.
 
    
 0.809
murA
UDP-N-acetylglucosamine 1-carboxyvinyltransferase; Cell wall formation. Adds enolpyruvyl to UDP-N-acetylglucosamine. Target for the antibiotic fosfomycin; Belongs to the EPSP synthase family. MurA subfamily.

narX
Sensory histidine kinase in two-component regulatory system with NarL; Acts as a sensor for nitrate/nitrite and transduces signal of nitrate availability to the NarL protein and of both nitrate/nitrite to the NarP protein. NarX probably activates NarL and NarP by phosphorylation in the presence of nitrate. NarX also plays a negative role in controlling NarL activity, probably through dephosphorylation in the absence of nitrate.
 
   
 0.774
narQ
Sensory histidine kinase in two-component regulatory system with NarP; Acts as a sensor for nitrate/nitrite and transduces signal of nitrate/nitrite availability to the NarL/NarP proteins. NarQ probably activates NarL and NarP by phosphorylation. NarQ probably negatively regulates the NarL protein by dephosphorylation.
