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

xylED-xylose transporter; Uptake of D-xylose across the boundary membrane with the concomitant transport of protons into the cell (symport system). Glucose is not transported, but can compete for xylose binding sites and can inhibit xylose transport (in vitro). Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family. (491 aa)    
Predicted Functional Partners:
xylA
D-xylose isomerase; Protein involved in carbohydrate catabolic process and glucose metabolic process; Belongs to the xylose isomerase family.
 
  
 0.930
fucP
L-fucose transporter; Mediates the uptake of L-fucose across the boundary membrane with the concomitant transport of protons into the cell (symport system). Can also transport L-galactose and D-arabinose, but at reduced rates compared with L-fucose. Is not able to transport L-rhamnose and L-arabinose.
  
  
 0.925
lacY
Lactose permease; Responsible for transport of beta-galactosides into the cell, with the concomitant import of a proton (symport system). Can transport lactose, melibiose, lactulose or the analog methyl-1-thio-beta,D- galactopyranoside (TMG), but not sucrose or fructose. The substrate specificity is directed toward the galactopyranosyl moiety of the substrate.
  
  
 0.910
xylB
Xylulokinase; Catalyzes the phosphorylation of D-xylulose to D-xylulose 5- phosphate. Also catalyzes the phosphorylation of 1- deoxy-D-xylulose to 1-deoxy-D-xylulose 5-phosphate, with lower efficiency. Can also use D-ribulose, xylitol and D- arabitol, but D-xylulose is preferred over the other substrates. Has a weak substrate-independent Mg-ATP-hydrolyzing activity ; Belongs to the FGGY kinase family.
  
  
 0.898
xylF
D-xylose transporter subunit; Involved in the high-affinity D-xylose membrane transport system. Binds with high affinity to xylose.
   
  
 0.892
xylG
D-xylose ABC transporter dual domain ATPase; Part of the ABC transporter complex XylFGH involved in xylose import. Responsible for energy coupling to the transport system (Probable). The XylFGH system can also transport ribose in absence of xylose; Belongs to the ABC transporter superfamily. Xylose importer (TC 3.A.1.2.4) family.
   
  
 0.877
xylR
Xylose divergent operon transcriptional activator; Regulatory protein for the xylBAFGHR operon.
     
 0.820
yajR
Putative transport protein; Protein involved in response to drug.
      
 0.786
melB
Melibiose:sodium symporter; Responsible for melibiose and other galactoside transport. It is capable of using hydrogen, sodium, and lithium cations as coupling cations for cotransport, depending on the particular sugar transported (symport system).
   
  
 0.652
xylH
D-xylose ABC transporter permease; Part of the binding-protein-dependent transport system for D- xylose. Probably responsible for the translocation of the substrate across the membrane; Belongs to the binding-protein-dependent transport system permease family. AraH/RbsC subfamily.
