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 (repressor) 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
Regulator of 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.

barA
Sensory histidine kinase; Similar to E. coli sensor-regulator, activates OmpR by phophorylation (AAC75828.1); Blastp hit to AAC75828.1 (918 aa), 90% identity in aa 1 - 918.
 
 
 0.948
uhpT
MFS family hexose phosphate transport protein; Mediates the exchange of external hexose 6-phosphate and internal inorganic phosphate.
  
 0.933
yhjB
LuxR/UhpA family; similar to E. coli putative regulator (AAC76545.1); Blastp hit to AAC76545.1 (200 aa), 72% identity in aa 1 - 200.
  
   
 0.919
csgD
Putative transcriptional regulator; Necessary for transcription of the csgAB operon. May have the capability to respond to starvation and/or high cell density by activating csgBA transcription (By similarity).
  
   
 0.863
narQ
Similar to E. coli sensor for nitrate reductase system, protein histidine kinase (acts on NarP and narL) (AAC75522.1); Blastp hit to AAC75522.1 (566 aa), 88% identity in aa 3 - 565.
 
 
 0.791
ilvN
Similar to E. coli acetolactate synthase I, valine sensitive, small subunit (AAC76693.1); Blastp hit to AAC76693.1 (96 aa), 90% identity in aa 1 - 96.
 
    
 0.762
narX
Sensory histidine kinase in two component regulatory system with NarL; Senses nitrate/nitrite; regulates anaerobic respiration and fermentation; similar to E. coli nitrate/nitrate sensor, histidine protein kinase acts on NarL regulator (AAC74306.1); Blastp hit to AAC74306.1 (598 aa), 86% identity in aa 1 - 598.
 
 
 0.761
torS
Histidine kinase; Regulates tor operon; similar to E. coli sensor protein torS (regulator TorR) (AAC74078.1); Blastp hit to AAC74078.1 (904 aa), 62% identity in aa 1 - 896.
