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:
some 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

setAInvolved in the efflux of sugars. The physiological role may be the detoxification of non-metabolizable sugar analogs. Can transport IPTG, lactose and glucose. Has broad substrate specificity, with preferences for glucosides or galactosides with alkyl or aryl substituents (392 aa)    
Predicted Functional Partners:
sgrR
Activates the small RNA gene sgrS under glucose-phosphate stress conditions as well as yfdZ. Represses its own transcription under both stress and non-stress conditions; this repression likely provides one measure of control over sgrR at the level of synthesis. Might act as a sensor of the intracellular accumulation of phosphoglucose by binding these molecules in its C-terminal solute- binding domain
 
   
 0.799
ydeA
Involved in the efflux of sugars. The physiological role may be the reduction of the intracellular concentration of toxic sugars or sugar metabolites. Transports L-arabinose and to a lesser extent IPTG. Seems to contribute to the control of the arabinose regulon
      
 0.641
sgrT
Acts to promote recovery from glucose-phosphate stress due to intracellular accumulation of glucose-6-phosphate caused by disruption of glycolytic flux or in the presence of (toxic) non-metabolizable glucose phosphate analogs. It may do so by inhibiting the transporter activity for glucose uptake (PtsG) as cells that overexpress this protein do not seem to import glucose although they have nearly wild- type levels of PtsG

yfgJ
Uncharacterized protein YfgJ; Protein involved in biotin carboxyl carrier protein biosynthetic process
  
     0.547
murJ
Involved in peptidoglycan biosynthesis. Transports lipid- linked peptidoglycan precursors from the inner to the outer leaflet of the cytoplasmic membrane. ECO:0000269|PubMed:18708495, ECO:0000269|PubMed:18832143,
      
 0.483
aaeB
Forms an efflux pump with AaeA. Could function as a metabolic relief valve, allowing to eliminate certain compounds when they accumulate to high levels in the cell. Substrates are p-hydroxybenzoic acid (pHBA), 6-hydroxy-2-naphthoic and 2-hydroxycinnamate.
